An interesting post
I dont consider it action oriented because it's more about the characters and their thoughts & way of thinking etc. And about the last 2 episodes, i partially agree with you. I agree that the last 2 episodes were a bit "slow" generally compared to the whole series, and can be boring (again, a matter of taste). What i dont agree, both about the last 2 episodes and the rest of your post, is sentences like this:
"Anyone who wasn't pissed of at the last 2 episodes and says "i understood it" is just being as pretentious as the show."
These are just your opinions, you do not need to force people to agree with you. I was like watching a arcade fighting game character doing 345345 combos and pwn his opponent.
And Ergo Proxy is a good anime, yes.
And i'm sure you agree with me if i said NGE is one of the most famous (in a good or bad way) anime series, and should be watched if you are really into anime. Just like Akira.
