I'm not going to watch it, just curious as to what it is. So it's like a more serious giant robot show. Like The Wire of Gundams?
Evangelion is a show with a bunch of interesting ideas. The mech scenes are mostly there for character development and are a tiny fraction of the story. The bulk of the story is a character study, and an analysis of all the characters and how extremely fucked up individuals they are. Shinji, the main character - the dude who beat off in that video - is basically a dude who was abandoned by his father at a young age to help develop the Evangelion project - the mechs. He is a very fucked up individual. Most, if not all of the characters on Evangelion are not likable, and that's kind of the point, as their lives spiral out of control as the show continues forward.
The problem is that the show mixes a bunch of psuedo-intellectual crap into the story to make it seem more deep, and far more pretentious than it should be. The show itself isn't bad.
There are far more dark mecha anime out there and I'd say even Gundam is darker than Eva depending on the series. It's not "The Wire" of mecha anime but it certainly propelled a specific new kind of anime television series.
