Spoilers:
There's a lot to love about MotU and the other Faerun content
however I just find all the deus ex machina tropes, and the futility of much of the actions very disheartening? frustrating? well less than enjoyable. I have come to absolutely loathe Elminster. Too much, too often, didn't matter what the characters achieved, didn't matter how heroic our actions to force the story along the DM/Narrator/Story-God swooped in and the girl gets kidnapped again, the scrolls pieces we made such an effort recovering get stolen back, etc.
From the very first quest, the rift we're trying to stop from opening... the ritual is completed with the drow's death - the writing makes the whole thing an exercise in futility that replays almost immediately with the Spinner of Shadows. And couple that with the way we reincarnate and replay quest series then the writing makes it feel like some punishment of Sisyphus. Always a hair too late, always your heroic actions are exactly what the bad guys wanted anyways... over and over. I blame the writers for repeating the same story trope and just redressing it for the different quests.
When you look at the bare bones of the story its a poorly written soap opera-comic. But its trimmed very nice in the setting, with gorgeous imaginative destinations. I love the Underdark, I even like the Demonweb when I know where I'm going and how to get there, I love the sumptuous set dressing and architecture of Sschindylryn (sp?), but I'm not a fan of the writing.
Ravenloft is almost the opposite. Everything you do, really matters. The items you need to take down Strahd, you really need and he never steals them back from you to make you retrieve them again somewhere else. Saving Ireena, the Sunsword, the final battle with Strahd where he really ends feels way more epic, intensely more satisfying than rescuing Ana and battling Lolth's belly button.
