just finished it, damn I didn't know an ending could have so many plot holes, lol, felt like I was watching a straight to DVD low budget hollywood movie... now I understand the frustrations of hardcore fans who have been through all the previous Mass Effect games, and I gotta say I feel lucky I'm not one of them otherwise I'd be pretty choked too, left all incomplete and unsatisfied, it's like banging a hot chick and just when you bout to bust you stop... I've only played ME3 not knowing fully the whole story at all, and the ending still gave me blue balls
this guy nails it pretty damn good in one simple paragraph,
Mass Effect 3 Ending Deconstruction - Twenty Sided
"If you are crazy enough to make a three-game series that ends on a black note with no questions (sensibly) answered and no sense of closure, then the least you can do is make sure the things you do say at the end doesn't contradict what has come before, or introduce new plot holes in the last minutes of the game. This is what Mass Effect did, and it's what has players so angry. Everyone dies, the bad guys turn out to be ridiculous, we don't find out what happens next, and the things we're shown don't make any sense. It is the most insufferably frustrating, obtuse, and nihilistic ending I've ever seen"
