User blog comment:Legionwrex/Did the Leviathan DLC really add a new twist to the endings?/@comment-5185748-20120904145702/@comment-213828-20120904195917

@Legionwrex: It's not that people are happy that's the problem. It's that happiness feels fake in the Synthesis ending. You're essentially giving into the Reapers' ideology that organics and synthetics can't work things out on their own when clearly they can. It also justifies the Reapers' genocidal cycles and lets them off the hook for the trillions of lives they've destroyed. That's not right.

And also, even if Synthesis brings eternal peace to this galaxy, what's to stop the Reapers from moving onto another galaxy and harvesting all the advanced civilizations over there?
