A Certain Scientific Railgun is a much better counterpart to Magical Index that feels like an intriguing cop show set in an X-Men-like universe. It’s still got a lot of anime pervery sins though.
Fireworks
An interesting, mysterious story that while gorgeously animated, feels more like a stand-out episode of a Sci-Fi TV series than a standalone movie.
The End of Evangelion
If you, like me, finished the main series thinking "Well, I'm not really sure what happened, but there's another movie to wrap up those loose ends" then this won't be too satisfying. While some questions are answered, it creates more than those it answers. It does have one of the greatest fight scenes I've seen in animation.
Neon Genesis Evangelion
Evangelion is what made Mecha a great genre, filled with existential psychological enigmas and religious imagery. It is easily one of the most influential anime ever to have been created.
A Certain Magical Index
Every anime sin is committed here in a show that feels like it was Frankensteined together out of everything kids in the early 2000s said they liked about anime.
Serial Experiments Lain
The unsettling lovechild of The Matrix and Donnie Darko (yet predecessor of both), Lain is an existential ride that is hauntingly more relevant today than when it aired 22 years ago.
Arpeggio of Blue Steel
Strategic Naval Warfare meets A.I. Becoming Too Human Psychological Exploration. Yes, the ships are waifus.
Plastic Memories
A good number of emotional gems stand out among cookie-cutter anime formula. Overall, it felt like the story, setting, and characters didn't match up right.
Fate/Extra – Last Encore
Monogatari-style plot, Fate functionality, and Final Fantasy-type Final Boss. Kind of a chore to watch.
Sword Art Online: Ordinal Scale
While not without plot holes and a slapped-together ending, this grounds the series back down to its roots and keeps asking those very relevant questions.
