I didn't mind the animation at all. I was referring to the
1. unlikable characters
2. use of laughable religious imagery to appear EXOTIC to western audiences (KT pretty much admitted that all the cross-shaped explosions and shit were completely ridiculous and they regret adding it)
3. Pretentiousness (using "superflat" as an excuse to draw endless streams of childish innuendo)
4. Fucked up scaling for the Eva units even by Gainax standards (climbing up buildings in one scene and stepping over them in the other)
Some people can look past this and enjoy the show, but it's not flawless and untrollable.
