I think you nailed why I dislike the ending.BloatedGuppy said:And I find this to be a problematic rewriting of history as well. I don't even like 99.9% of my favorite game of all time, and I most certainly do not find 99.9% of Mass Effect to be above complaint. Most certainly I do not find 99.9% of the third game to be flawless, which is an absurd statement...much has been written here and elsewhere about myriad flaws that had nothing to do with the ending. It was a workmanlike but somewhat troubled effort that can most charitably be described as "uneven", marrying moments of near-brilliance with occasional rubbish. Even the well loved first and second chapters are not without issues.
But this isn't a question of determining whether or not ME was 75% or 99% strong before it fell at the finish line and died. There is no more essential element to a story than an ending. End it badly, and you HAVE compromised the work as an entire. If at the end of LOTR Frodo woke up in the Shire and it had all been a dream, you'd not be hearing much about those books as classics. Probably the most common charge leveled against the ending presented to us in ME3 is that it turned the entire saga into a shaggy dog story. I don't know if that's entirely true or fair...if you reach, you can find traces of some of the themes they turned to in the 11th hour in some of the DLC and some of the happenings in ME3...but it certainly wasn't narratively or thematically consistent. If it was "functional", it was functional only insomuch as something ended. With a great, wet splutter and a puff of fumes.
I think it's fairly evident that someone...whose name may or may not rhyme with Macy Pudson...had been watching a lot of Moon and Solaris, and decided he didn't really WANT to finish making Star Wars for a new generation, he wanted to Arthur C Clarke that ***** up with some technological singularity and transhumanism. Make him some art! But it's rather like shoehorning the end of the Decalogue onto Die Hard. Rather than a natural conclusion, we're left with a strange atonal lurch. All themes of galactic unity in the face of overwhelming odds, writing the wrongs/healing the wounds of the past, mending fences between disparate people, etc are tossed aside while you chat with a glowing kid (who is also the primary antagonist) about which bizarro ending you want. At least one of which involves the exact horrifying bio-mechanical fusion you've spent the better part of 3 games trying to avert. It is a misread of colossal proportions when it comes to audience expectations.
Personally, I think BioWare wrote themselves into a corner and simply could not end it with a reasonable victory. Lord of the Rings did a good job setting the stage for why the ring was invincible except for this very small volcano in the heart of Mordor. The quest was challenging, but doable. BioWare never did that with the reapers. At no point in the series did I ever think, wow I really have a shot at beating these guys. 1 reaper pretty much destroyed the entire galactic fleet in ME1, how could we ever possible win against hundreds or thousands of them? Other than assuming they were killbots with a kill count limit, BioWare never created conditions for victory.
I also think this is why the ending resonates so poorly with me. I have played 3 games with a nearly invincible foe, only to find that they are controlled by a glowing child and exist for some escoteric reason. The Blair Witch Project was an incredibly popular movie- and yet you never see the villain- and that's what makes it scary. Instead imagine that rather than having the fear of the unknown, the directors had shown the Witch. There is nothing they could have down to match the expectations of the audience. BioWare "showed the witch" with the ending of ME, that is, they tried to unmask the reapers, and by doing so stripped them of their horror. The ending then became about some stupid robots and bizarre robot logic, rather than an unfeeling foe that allow us to exist.
