The Mass Effect 3 fallout was something else, but there was a lot of valid criticisms with the vanilla and extended cuts of it. Walters and Hudson couldn't see beyond their "brilliance" to realize how shallow their writing actually was. Besides "Synthesis" is what we fought Saren against in the first game so how could that be the "true" ending? There's too much to whine about it.

This is why I actually like the renegade ending the best.

"Oh so after you went and just killed FUCKING EVERYONE you expect me to abandon my original goal for some reason? FUCK no! You gonna DIE!"
BLAT BLAT BLAT KABLOOIE!!!!

I always interpreted the Synthesis and 'Hero' endings as the Reapers trying to trick you into letting them live.
