Any opinions on this matter would be helpful.
I would definitely recommend watching the series, it can be a bit slow at first but picks up a lot of pace near the end, its worth it just to watch end of evangelion which is one of my favourite anime movies
As I said only need to watch 1-24 and end of evangelion
not really spoilers?
only thing to take from episode 25-26 was a single mention of the human instrumentality project , you find out in end of eva but it helped to know all the way through
the rest of those episodes are very overused shots of characters in the dark asking stuff like 'who am i?'
