The whole controversy over Mass Effect 3's ending is picking up a feverish pace at this point. One of the things I'm finding interesting is that many players are finding wrong with nearly the exact same things, which I went over a subset of yesterday. Usually when fans get upset about storytelling in games, you'll get a host of things they thought were wrong. A more literary example - ask a hardcore grumpy Tolkien fan what they didn't like about the movies, or what should have been in them: you'll almost always get "Tom Bombadil" ... but also fifteen other random things.
P.S.: Also consider GameFront's article on this, which is quite excellent.
