I've been hearing a lot of hate to how ME3 ends for days, but never dug in dig until I experienced it for myself. I finally did beat it and honestly, I didn't think the ending (or at least the one I picked) was so bad.
Now I didn't think it was the greatest ending ever and I wasn't like standing up and applauding it either. I guess I had no real expectations as to how it would end. I figured I'd at least stop the Reapers, which I did. So at the basic level the ending delivered for me. I also hear everyone saying that the choices were completely thrown away at the end. While none of them seemed to really surface in the final assault, I didn't feel it was lacking as a lot of those choices would have little relevance to a large scale military strike. I dealt with the conclusion to issues that have been around since ME1, and made those conclusions to gain support for the final push against the Reapers. The fact I wasn't reminded about them all as I fought hordes of husks didn't really bother me.
I guess I'm mostly confused on how so very many are demanding a rewrite and basically saying the game was garbage just because of the last ten or so minutes. I for one had a great time playing through the 30+ hours. Lots of great character moments, acknowledgement of where I started and what I'd been through (Or rather my Shepard but you get the idea). Plus there were a lot of epic, heartfelt and sheer badass moments sprinkled through the game. So given all that content I'm just baffled how so many can claim it for terrible because a small portion, granted a key plot moment none the less, wasn't what they expected.
(( 3-19-2012: After giving the endings more thought and cooling off after the whole "I beat it" feeling I'm starting to side more with those who are upset over this conclusion. I'm still not enraged as the fun experience up to the final moment was awesome but I am more disappointed now at the real lack of, and confusing closure. It is a pity it had to end like this but I'll still regard the series highly as few other games have gotten me as invested as Mass Effect. ))
