Neon Genesis Evangelion

Can someone point me to a youtube video or something else that explains what happened here and in the movie? I am very confused. Also pls lmk if I should watch all the alt movies

Bearded men nuke south pole to cure depression through aliens

Finished this one quite a while ago but

• If you understand the plot then you possess a quantum computing brain
• OST is great
• Artstyle is great, unless you like anime where they blow half the budget on the hair
• Absolute classic
• more confusing than King Crimson
• personally I enjoyed it very much
