Frozen

Initially, Roz was annoying when she kept asking the animals if they needed her assistance. She's so advanced, can't she tell they are not humans?

It takes a lot of suspension of disbelief to accept that Roz could learn how to speak to animals in chirps/grunts/growls etc. If such technology exists...the world would be very different, Roz shouldn't have been the first one to discover it. There is also an inherent assumption that all the animals can speak to each other which doesn't make sense. Intra species, yes, but not inter-species. A bird can't speak to a fox.

I'm alright that the baby goose imprinted on to the robot. It's a main plot point and selling point. But later on, when the film revealed that there were THOUSANDS of geese on the island, I started to scoff. Did Roz, Fink the fox and Brightbill the young goose NOT know that there were other geese? Didn't hear them? Didn't see them flying? And the geese somehow knew that his family had been killed by Roz? Why would they know that? And why wouldn't the geese try to save Brightbill from Roz, whom they viewed as a monster? And why were the geese mean to Brightbill like school bullies?

The big betrayal where Brightbill left because he discovered that Roz hid the fact that she accidentally killed his family, did not hit the right way it should. It felt off and was just there because the plot needed it.

I doubt one week's worth of flight training would get Brightbill fit enough to fly a migration flight. Also I don't think a bird of prey can teach a duck to fly.

Brightbill taking over as the leader of the geese did NOT make sense. Again, the plot required it. Was there no second in command to the leader of the geese? Brightbill is a teen, he hasn't even flown the migration route before, how can he be the leader? Even if we allow for some innate electromagnetic sensing of the flight path, he still is very young and would not be able to make decisions on where is the best place to land etc. And we did not get to see the old leader goose go out in combat. The scene just abruptly cut to Roz. Why would the old goose willingly sacrifice himself?

The hibernation/winter scene does not make sense for so many reasons. I don't think the log "cabin" that Roz made would withstand such a terrible winter. (gee Elsa, warm up a little? 😂) but the BIGGEST PROBLEM is the number of some of the animals depicted. There's ONE fox? On the whole island? ONE beaver? ONE bear? One mama opossum but no male opossum? How the heck do these animals reproduce? How did they get to the island? If there's a main land where they came from, why wouldn't they go back there to seek shelter before winter? (oh, but in the scene that the raccoons steal parts from Roz, there were like 100 raccoons? Doesn't make sense! How does the island support so many raccoons?) Next problem, I can't believe they would all not eat each other while in the log cabin. Please, that is totally unrealistic. (going forward, how do the predators stop eating meat? They can't just convert to eat vegetation) And if you interrupt an animals hibernation like that, can they just simply resume hibernation for weeks in that cabin? Does the fire last forever? (in the ending of the film, we see a fire in the rebuilt log cabin - who started the fire? Animals can't make fire!) Also, characterizing Fink as being disliked by everyone else is too similar to Zootopia.

The scene that a crocodile (or was it a predatory fish?) was chasing Brightbill, and Roz saved him but damaged her foot - there were other geese in that same lake. If there was such a dangerous predator in the water, there is no reason the geese would swim there. If I recall, immediately after Brightbill was out of danger, we see geese on the water again. Inconsistent. The predator is only predatory when the plot calls for it.

Roz was depicted more than once to be "injured" or even near death but nothing came out of it. I recall that she seemed to be leaking hydraulic fluid and Fink was looking concernedly at her foot prints. This sets up the audience to think something bad is going to happen. But nothing did. After Roz collected all the animals into her cabin, it looked like she had accumulated too much damage from being in the cold and was on the brink of death. But no, spring came and she was totally fine. Later on, she yanked out her "core" while saving Brightbill when falling from the sky. This seemed to be the poetic ultimate sacrifice. I thought she'd be dead for sure. But no. Nothing happened. She still functioned and could even rebuild the log cabin. You can't lead the audience on like that repeatedly and not deliver! Fool me once... But not 3 times (or more)

The "evil robot" Vontra - there is no reason she is so seductive and so evil minded to pick up a gun. She's a robot. (similarly why do the warrior robots have deep male voices) During the fight scene Roz activated some device that (I can't recall exactly) magnetized Vontra or sucked her up by some force - why wouldn't that affect Roz too? That's cheating.

Robots vs ducks - why would the robots not have a more efficient way of taking down a large number of fast flying assailants like some kind of shield or electrocution? I remember the robots using a single laser gun to try and shoot down the birds one by one. In the greenhouse, the warrior robot caused damage to the greenhouse - surely the humans who built it would have planned for infestation and a means to control it without damaging the greenhouse.

Earth in the movie was not fully explained. We got one scene of the Golden Gate bridge under water with whales swimming on top of it. Poetic and thought provoking, some kind of post apocalyptic earth? but no explanation was provided. Early in, Roz takes out a brochure for a Florida vacation. So... San Fran is under water but Florida is not? We see a corn field in a green house, that's it. No explanation. I suppose it's all in the book (I have not read) but as a film, it must stand alone. Film viewers should not have to read the book to understand. Who's making these advanced robots and ships? What is the message being sent here? Wall E - lazy humans who have programmed robots to do everything? Is there an evil mastermind who also makes the warrior robots? (those robots looked scary) oh and by the way, the animals being able to defeat the warrior robots was ludicrous. Yes, I know that Roz adopted animal behaviors to beat the robots but come on. Roz is already stronger than the animals (she could carry the bear) and the warrior robots would be even stronger. But they can be beaten by animals. Roz's "skunk" spray should have zero effect on the warrior robot.

The beaver that was gnawing away at the tree - the way he was making a hole under the tree from one side, at some point the weight of the trunk would have collapsed ON him, not away from him, no?

The ending was the most disappointing part. Roz gives herself up and... Becomes a corn farmer. Brightbill comes to visit her periodically. It was not fulfilling or satisfying. What happened to all the knowledge Roz amassed? The fact that she developed emotions? Why was she allowed to survive? Wouldn't the humans have taken her CPU and recycle her? She was badly damaged and dirty, missing her core etc. Also the reunion felt a bit too reminiscent of the last scene of Baymax (big hero six) when the robot recognizes the main character.
