1.0 is a perfectly adequate adaptation of the first 6 eps with a nice upgrade for best girl Rami-chan. 2.0 differs from the anime in that it focuses heavily on Rei and Shinji's relationship while more or less sidelining Asuka, who's now a played-straight tsundere minus her character-defining tragic backstory. I've even read that at some point in the development process they were debating whether or not to include Asuka at all, and ultimately put her in because of how iconic she is to the franchise... but I don't have a source for that on hand, so take it with a grain of salt. Personally I'm alright with this since the anime still exists if I want a story that focuses more on Shinji and Asuka. And while it would've been nice to get a more-or-less straight animation upgrade of the anime (god knows some of the animation has aged poorly), I'm not opposed to the idea of telling a new story using the same characters.
3.0 is... complicated. It throws a fuckton of questions at you and introduces a ridiculous amount of half-explained lore while not really answering anything, having characters acting seemingly extremely OOC, and not giving everyone's favorite waifu Mari a single ounce of character development. I personally don't like it all that much, but the movie's production history sheds some light on WHY 3.0 is the way it is. Namely, it was originally intended to be released as a double feature alongside 4.0, each about 40-50 minutes long. Meaning, there's a good chance that the original plot of 3.0 was literally written with the intention of it being half a movie. This wouldn't have been too big an issue had 4.0 released when it was intended, a year or two after 3.0. But we're at 8 years and counting, which is way too much time to hyper-analyze a movie where most of the answers boil down to "we just don't fucking know, there's just not enough information".
This knowledge gives me hope that 4.0 may pay off on 3.0's ideas in at least a somewhat satisfying way, because it suggests that the two movies were planned as two parts of one story, unlike say the Disney SW movies where meaningless plot points are introduced with the hope that the next writer will figure something out with them and retroactively make them important, with the writers and the audience equally in the dark as to how the story is going to end. Thus, I'm going to hold off judgment on it because I honestly think that if 4.0 is good it will retroactively remove most of my gripes with 3.0, which stem more from a lack of clear information and context rather than any plot points in particular I find inherently objectionable.
