Ugh, I just finished the game and I did not like the ending much at all. I kinda assumed Shepard would die and was fine with that, but the three choices were all really dumb for different reasons. I ultimately choose the goofy Space Magic third option, but it was unsatisfying as all hell. Now Joker and EDI are marooned on some empty world forever, and all stellar society is basically collapsed for untold millennium? Fuck off.
And the other endings were non starters for me, I didn't bust my ass over the past two games curing the genophage, solving the Geth/Quarrian war, freeing the rachni, etc etc only to kill all the synthetics. And how does controlling the reapers help? And why did I spend so much time finishing every side mission and maxing the Alliance forces? If I hadn't I don't see what would have been affected, Shep has to get to the Citadel no matter what so it's not like ME2 where maximizing my squad meant I kept them all alive.
I haven't seen the other two endings yet but they all seem 'bad' to me simply because it's my understanding (from the Catalyst, who took the form of the kid, UGH) that you destroy the relays no matter what. And the thing I LOVED about the ME universe was, uh, the mass effect relays and the galactic civilization they allowed to exist.

I didn't really care which characters lived or died that much, but if no matter what I send the galaxy into solitude and shit (with even the closest major neighboring worlds hundreds or thousands of years away if you can pack that much eezo onto a ship

) And why the fuck was the Normandy traveling FTL at the end?
Ah well as soon as I finished the game I went and bought Journey. It should be installed by now, should be a good palate cleanser if nothing else.
