@The Admiral. My apologies for not giving warning about all the foul language that was in the video.
I've finished the game and I definitely understand the frustration and even anger some people are feeling.
keep in mind that this is a game that has sold itself principally on the idea that it is an extended RPG/adventure story (with a bit of third person shooter mixed in) which you as the player have a fundamental role in shaping.
Your decisions at every turn are meant to count. Choices from earlier games come back to reward or haunt you in later games.
You are meant to invested at an intellectual, and even emotional level. That's what brings people back to fork out their hard earned cash.
I thought the ending was cr*p to put in mildly, and it wasn't because I wanted a puppy dogs and fluffy kittens option.
It was because in the last 5 minutes of the game Bioware shredded everything that had had been built up to that point. It seemed to fumble and fail in every possible way, and on every possible level.
It was like the last bit of the story was written by some moderately talented 13 year old scifi geek/wannabe writer who had only been told the rest of the story as a ten minute verbal synopsis by his gamer mates, before tacking on his misshaped piece of polished poo.
It tried to be more epic than epic while making almost no sense.
It threw away all the richly developed characters that you had worked with and against without a second thought.
It rendered several of the fundamental achievements that you had worked towards as pointless.
It gave you a moderate array of convoluted and abstracted choices to end with, all of which made your sacrifices and choices seem somewhat more universally damaging than if you had simply never gotten involved. Seriously. When I understood the the broader consequences of each choice I couldn't see how simply letting the Reapers win would be more harmful.
