The first set of videos seem to be negative criticism for the sake of negative criticism. The way he goes on about Mass Effect is the same way anyone could go on about any fiction, good or bad. Also a lot of his points that he goes on about for 5-10 minutes are easily answered by plot revelations, simple facts and some critical thinking. If he took as much time actually paying attention to the plot instead of finding ways to harp about it, he may have saved himself 75-90% of the time it took to make his videos.
Squee's video is very on point, with actual supporting points and is fairly impartial. Also seems to have a lot more knowledge about the story and the facts of the story/plot. In a way, Smudboy should take some pointers on the way Squee supports his points. Pretty much essay format.

I watched the third video link too and it was meh. It doesn't make a case that the marketing is bad or wrong and how it could effect development in any way. Instead it takes insignificant quotes and clips, blows them out of porportion with "special effects," alienating cut offs, alienating music cut ins, and meaningless criticism. The focus on the Omniblade was pretty bad and quite sad.
I think Smudboy was initially rubbed the wrong way by Mass Effect 2 and his opinions got even more extreme over time until he saw what he wanted to see: The worst story/writing ever.
