Oh, oooooohhhhh! I know I just posted but I thought of a much better answer- Severus Snape. If you've been living in a cave and don't want to see Harry Potter spoilers stop reading now.
So Snape spends most the series acting nasty and kind of evil but still in a slightly ambiguous way. That's fine to begin with bit it does get a bit dull eventually, luckily there's a payoff in the form of a small amount of backstory being revealed quite a long way in and then a great big revelation basically as the series ends.
It turns out Snape had a difficult time at school including being bullied by James Potter and having a crush on Lily that basically goes nowhere. All kind of sad but not enough to form a whole character around. Except that the big revelation at the end is that he's a double agent, pretending to help Voldermort at the request of Dumbledore, fuelled by a desire for revenge for Lily's murder. He does a hell of a lot of bad things because of this, stuff he doesn't want to do, basically because he hasn't been able to get over the fact he and Lily were never together. Still it'll all be worth it to take down Voldermort. Except that actually he doesn't end up doing anything useful to that end before he is killed. In fact his last act is to try and clear his own name and again bring up how sad the whole Lily thing made him.
To me all of that just seems kind of pathetic. He spends his whole life being miserable and doing things he doesn't want to do, largely on the basis that he couldn't get over a girl, only to die before he can do any good or even see his enemy fall. It's certainly sad but I don't see how any of that translates into the Snape love that exploded after that revelation. Alan Rickman love I can totally get behind, he made Snape 10x more engaging than he was in the book for me, but I flat out don't get all the fans of Snape who think he's the best character in the whole thing.
Also given these last 2 posts I imagine I'll need to change my identity to hide from all the indignant fans I've annoyed. Could be worse though, at least I didn't say anything bad about Boba Fett, Mario, or Chell, then I'd really be in trouble with the internet.
