Extra Credit is a bunch of pretentious, pseudo-intellectual dribble blatantly pandering to members of the equally pretentious and pseudo-intellectual "games are art" movement. Many legitimate points EC might have made in most of their videos are almost immediately drowned and crippled by pompous and almost smug over-analysis that strikes me almost as parody over-analyses. Even further, their analysis is usually accompanied by total misinformation, the exploitation and stretching of facts to suit their given argument, or outright making up points and expecting the audience to merely accept. This results in a serious look at the show to reveal tons of holes in their logic which just goes to outline their pandering.
Overall, it's overly pandering to the rubbish "games are art" people without even attempting to hide this blatant and despicable pandering. If EC is not intent on being so far up their own ass, then they can make decent points, but this seldom happens as they have to maintain an air of suffocating pretentious in order to appeal to their core demographic.
I know I said pandering a lot, but that's ALL the show is: pandering to the "games are art" people.
