He didn't do it.

The cops very clearly planted evidence on him because they had to make an arrest because all eyes were on them and whoever actually did the deed was making them look stupid.

Why would the real killer hero have kept the weapon on his person and traveled two states over while carrying it and a manifesto in his bag, conveniently turning the crime into a federal matter? The same guy whose bag they found in a park, filled with monopoly money? Why did the police turn off their bodycams, take Luigi's stuff, drive a block away, turn their bodycams back on, go back into the restaurant, and then arrest him?

I love the way unions are framed as love for your community, and how community is the moral of the story but also showing the dangers of the media preying on people who want that sense of community. I love the friendship between the two main leads and how their personalities realistically clash but how they love each other at the end of the day and are willing to go to hell and back for each other.

I love the examination on how everyone loses in the system, from the people making the clothes for dirt cheap in other countries to the shipment drivers who don't get jobs because the company would rather invest in scifi technology then pay and wait to the store employees who see a fraction of the overall cut to the creative visionaries whose work goes taken and uncredited because of a figurehead and even to the assistant who is putting up with it all for the chance at being a boss.

I see the blatant commentary with making the main antagonist a wealthy white woman and a minor antagonist a white gay man who uses "progressive" language to talk down to his employees of color (or the figurehead of the union eventually being a light skinned woman of color). I love this too, especially paired with the backstory made for the wealthy white woman with implications of her being an underage victim of a white man but still doing massive amounts of harm as soon as she is the one in power.

There is probably a lot more I could be talking about but I don't want to spoil too much for those who want to see the movie plus I know there are things which flew over my head.
