I don't know. Colonel Sanders didn't really piss me off as much as ME3's ending did. Probably because I was FAR less invested in it than I was in the game.
You can say what you want, but ME is all about choice and consequence. More specifically, YOUR choices and consequences.
A movie's just a movie and even if it's a trilogy, the most you'll sitting there for is about 9 hours. You can have an opinion on it, but in the end, it doesn't matter. The movie played out how the writers/director wanted it to. There was never an participation on the part of the audience. On the other hand, let's say about 30/40 hours per ME game, where you decide who lives/dies and many other options. That's 90-120 hours of investment on your part.
