Haha you know, I've always loved wolves since I was a kid but that didn't really play into whether I really liked the character of Lupin. I was kinda neutral when it came to Lupin. He was kinda just there. Then I started disliking him in Order of the Phoenix and I down right thought he was an idiot in Deathly Hollows. My problem with Lupin is that he doesn't take action or at least with out taking into consideration what others will think of him. (Then I look at Sirius and remember the reason why I like him is becuase all he does IS take action even with out thinking ) So to answer your question: I don't hate Lupin but I don't exactly like him.
XD I like MOVIE Lupin. Unlike dumbass 13 year olds, there's more to an actor than just looks I love wolves too...I actually love dogs tons more (No duh I'm goanna love Sirius then) you're right though. It seems right after he had a baby and wife he was willing to freaking be an actual man.
