Finished watching the last two volumes of the anime, "Melody of Oblivion", last night.
As of the end of volume 4, I would have given this series absolutely glowing reviews. I would've been praising its quirkiness - the way it takes a fairly ordinary human savior versus evil monsters plotline and then twists things just enough to makes for this interesting, surreal, oddly seductive sort of a setting. There would have been a few negatives, mainly involving the over-the-top-ness of some of the human villains, but overall, the positives far outweighed the negatives.
And then I hit the final volume. And what had been "surreal and oddly seductive" crossed a huge line into crack-spawned and weirdly perverted. The storyline, which was a bit vague around the edges up to this point but at least kept moving steadily forward, just sort of hit its climax point and sputtered out in a smattering of bizarro imagery and random mumbo-jumbo. Some really interesting plot threads got added late in the game...and went nowhere. Fan-servicey content, which up to this point had been rather blatantly amusing, turned sour with some rather over-the-top scenes that didn't *show* anything but were still rather tasteless, imo.
I've never had the final volume sour me so much on a whole series. After the way I felt about volume 4, even a mediocre conclusion would have left me generally happy and ready to buy the series for my collection... but now I'm not so sure. *sigh*
