Finrod has bad qualities? Do tell - I'm not that well-versed in the Silm. As for disliked characters, I'm not that impressed by the Valar in general. For supposedly higher powers, they're fairly stupid and impotent, most of the time. *ducks* Sorry.

Thingol is a somewhat twisted character, true, but we must also be take under consideration that we aren't really told the things he actually did well... assuming there were such things. I wonder how much the fact that he was married to one of the Lesser Powers distorted his veiw on the world in general.

I find Harry Potter as a fandom boring, but you're right about both Remus Lupin and Hagrid.
