I think Remus as a character kind of reflects what Remus would be like as a real person: he doesn't jump out at you straight away as someone particularly interesting or special. It's only when you get to know him better, or have a think about him, (or reread the book!) that you start to notice all the great qualities he has.

I kinda like the fact that Hermione appears all goody-goody, but she can be really quite nasty when she feels it's warranted. I wouldn't want to get on her bad side. :)
