Just finished ME3, checked all 3 endings
While I don't feel that Bioware ruined my childhood, by raping puppy in front of my eyes, I now understand why people have problems with the endings
My main problem is that reasoning behind Reapers attack reminds me of Inquisition logic
And solutions make even less sense
Also- why mass relays needed to be destroyed? As far as I understand, developers will make other games in ME universe, so even this makes little sense.
So my main problem is that everything in last act makes no sense.
Should developers remake ending? Hell, no (like already has been said- it is bad precedent. Bioware, good luck salvaging this trainwreck up

)
I think that next ME game will start with the task of rebuilding mass relays.
P.S. As for those who RAGE over the ending. Guys (I won't even pretend that there are any girls in top tier of rage- there aren't) if you go to closest window and open curtains there is whole world outside, you know, outside (it is like your room, only bigger). And in this "outside" there are blue skies, sun, stars, fresh air and occasionally you can see some pretty girl walk by. So maybe you should do more "outside" and less gaming? I know, I know it sounds like heresy, but it should calm you down. So please, for the sake of us all, try it!
P.P.S. One thing should be fixed though, in the ending sequence characters who died in the last suicide run, shouldn't appear. Before entering teleporter I saw Ashley lying on the ground, but in the end she was climbing out of Normandy. Apparently her plot armor can resurrect and teleport her. Replace her with other human crewmember, like Samantha Traynor, please.
