hmm, the problems I have with the endings is that they make absolutely no sense and contradict heavily with lore already established early in the game, kinda a shame that such a well written series flops at the climax, I was pretty upset at first, but I'm over it now.
Bioware has been advertising since day 1 how the choices players made would decide how the story concludes, but they didn't deliver in the end, I can understand why people are angry, I do agree Bioware should take a lesson here, but still, ME3 is a great game nonetheless and this kind of backlash is ridiculous.
