I don't necessary care for a "happier" ending, but the fact that this isn't the whole "lol Catalyst and other dumb shit" ending is what interests me. For all I care, the game could end right
when Anderson and Shepard are dying and it would still be better. Their ending is bad, inconsistent writing, and the EC only makes it worse-- because they take their bad writing and add insultingly huge amounts of 'detail' to it. I return to my favorite example,
your nice, tender, minute-plus scene with your LI while Harbinger is in the background blasting people to death. People who aren't you or the Normandy, which, you'd think, would register higher on the HOLY FUCKING SHIT KILL IT scale
But yeah, I don't think the ending needed to be happier. That wasn't the issue, at least not for me. The sacrifice and all that was kind of poignant.
EDIT: Also, no, it's not idiotic. It's just what some people wanted to see. There WERE casualties. That wasn't my particular problem with the ending, but it's not even close to idiotic to have expected something more in line with the rest of the series' tone. Knowing that this mod exists and that I won't have to truck through Bioware's pile of dog shit at the top of an otherwise glorious mountain of awesome has reinvigorated my desire to play the game.
