Shinji Ikari as of Evangelion 3.33 was a huge disappointment, much like the movie itself.
At the end of 2.22, we see Shinji (who has now harnessed Spiral Energy, row row fight the powa) bring an unpowered Eva back to life on willpower alone in order to save Rei. Not because anybody told him to, not because anybody forced him to, not because he had no other choice, but because he wanted to. This is an enormous step for his character, one we haven't really seen in any canon incarnation of Evangelion yet. His willpower is so strong that Unit-01 goes into fucking god mode and nearly causes the third impact, before being struck by a spear which was thrown by Kaworu. So what did they do with this character? Show us the adventures of the new heroic Shinji to see what Evangelion would be like with a shred of positivity in it? Deconstruct shonen-esque heroics as seen in TTGL or DBZ to stick it to all those "Shinji becomes badass" fanfiction writers? No, they retcon the events of 2.22's finale and don't explain a single fucking thing.
At the start of 3.33, Shinji and Unit-01 are in a box, in space. Why? It isn't explained. Rei is also dead, despite the fact that we clearly see her getting saved at the end of 2.22 with zero foreshadowing that this wouldn't be the case. Why? This isn't explained either. Also, the "near third impact" happened, despite the fact that we see the halo above Unit-01's head (which signifiy an impact event) disappear at the end of 2.22 and no explosion was seen. Why? This isn't fucking explained either, and let's not forget that many major characters were within a mile of the retconned-into-occuring impact event when it happened. They must have all fallen into a plot hole the size of Giant Naked Rei before the explosion occured.
Anyway, Shinji is back to the same way he was in EOE and the last third of NGE. An almost lifeless corpse, a shadow of his already-pathetic former self. And the rabbit hole continues going deeper until he more-or-less IS a lifeless corpse that just happens to be capable of walking. We already fucking did this you guys, I thought the Rebuild of Evangelion was supposed to be something new. Well, I guess you could call this a new low for Shinji, but that doesn't make his character development here even remotely interesting. This is what annoys me most about all the people who work at Strawman Incorporated who cry "you just wanted more of the same!" every time I explain my disgust for the newest Evangelion movie.
While we're at it, can I just say EVERYONE in Evangelion 3.33? Major characters who work with Wille are reduced to a bunch of fucking assholes with zero depth and character development. Gendo Ikari is still doing his "still according to plan" shtick, another example of wasted potential. Mari is still a fanservice character who contributes nothing besides cat smiles and tits. Her and Asuka are still 14 years old for some fucking reason, and the unexplained "curse of the Eva" excuse couldn't be weaker. Hurray for cheap pandering.
What a fucking mess this movie was.
