Never really had a final boss "redeem" a game for me. If I'm liking the game the final boss either raises that good factor even further or tanks it a bit but doesn't ruin the game.
I've had some final bosses ruin games for me though. Final Fantasy 3's final boss is some right bullshit that forces you back three hours because you didn't know she had a gimmick and used the wrong damage type on the wrong add, combined with the difficulty curve in that game being a sharp spike right at the end and it's just not fun. DS3 was a game I was very mixed on when I first played it and only soured on over time, but the final boss music being REMEMBER GWYN REMEMBER PLIN PLIN PLON and being sad garbage to end an experience combined with the last phase being less of a challenge save for the one five hit move cemented my dislike for the game and it's nostalgiabait horseshit. Thought I'd get a cool amaglam boss of all sorts of character builds but no, had to have some damned DS1 nostalgiabait in there as if we didn't have enough of that during the rest of the game.
There are some final bosses that I thought were really awesome but don't get enough credit for their quality, though. Like Remnant II's final boss, Annihilation, having the really cool reality-switching thing and relying mostly on audio cues while remembering what's coming next, all while the phases keep switching in time to the music during the second half.

Autumn pisses me off in a ton of ways. Much more than just being "some dude in a trenchcoat". He flip-flops on his ideals and motives constantly not as a character point, but due to retarded writing and wanting to force him into being a villain but still giving a passive way out of his final fight because past fallout games did that.
If you actually wanted his Enclave to be a force trying to take the wasteland and rule it, give an evil or neutral karma option to join him when he kidnaps you started by giving him the correct code instead of having him dome you for it, and don't make him shoot a random passive scientist if his goal is to have a good rep with the wasteland and act as the benevolent dictator of such.
If you want him to be an irredeemable piece of trash then go all the way with hit and don't have his motivations flip at the last minute. And make his final fight an actual hard one like Frank Horrigan and the Master were, not some jobber with a 10mm pistol.
FO3's got a ton of problems but how they don't let you side with Autumn's Enclave is a big one for me, because for all intents and purposes he should be considering it with how much of a one man army your character has been, and since his goal is domination and not some purity shit like whatever Eden was smoking.

A reactor that you interact with is the final boss. If you want to be more generous it's the black-armored Synths in the non institute routes, and General Maxson in the Institute one. Black armored synths with barely any more health than normal combat ones and a dude in some power armor who's no stronger than any other power armored BoS fuck, I might add.
