"Let's talk about the upgrades on Sokka's character from NATLA"
He is still the comedy relief on the show but minus the pessimism and negativity.
Because instead of a small minded sexist boy they made him an emphatic, emotionally available, intelligent man with savvi cleverness and a tender heart.
(I know he eventually becoming better was a character arc in the original but since they had to shrink the plot; this change made more sense).
We never saw him properly grief Yue on ATLA, and honestly it was disrespectful how he move on so fast and was already kissing Suki on the serpent's pass. And latter flirting back with Ty lee (wich is why boys hype up this character as a "back bender" ew 🤢)
But on the live action he takes it seriously and shows PTSD from loosing Yue and how powerless he felt for not protecting her. So it made much sense how he was constantly worrying about the safety of Katara and Suki.
He is the only non-bender in the gaang and at this point he is not even good at fighting.. He it's like the person sitting as a co-pilot passenger feeling anxious by being there watching how others take the risk.
It was so wholesome how he opened up with Katara about their grief for their mother and Yue (while drinking cactus juice). 😅
Also, their sibling dynamic it's on point always bantering and teasing each other..
He awkwardly avoided Suki at first but his relashionship with her it's already looking more serious since he is healing before accepting her feelings for him.
I always tough Suki deserved better (than to be a rebound) and now she has it..
Did I mention this Sokka expressed his liking for shopping, purses and refined silk fabrics? He is a confident guy with taste ✨👌
Anyway they made Sokka very likeable; his ability to bond with side characters like Sai, and the lowkey bromance with the Professor were nice, he even offers to listen to Aang's worries and acts like a reliable older brother now.
That's all.. Thank you for coming to my ted talk ^^
