I don't dislike the books/films either. I will admit that the phenomenon left a bit of a bad taste in my mouth at first, though. This had less to do with the success of the series (because, why should I care unless someone is giving me money or taking my money) and more to do with a lot of friends and acquaintances trying to shove them down my throat. I read the first book at the urging of a friend that insisted that I would love it. It was ok...I didn't hate it, but I had no desire to read any more of them or see the films.
I felt that it was "fantasy soup" (bits and pieces from a variety of folklore and other fantasy fiction) distilled down to something that's accessible to kids and folks that aren't fans of most fantasy fiction. Nothing wrong with that, but the 'Potter fans relentlessly pestered me to give it another chance, insisting that, "you like fantasy fiction...how can you not like this!?!?" After a while, it just started to get a little annoying. It wasn't for me, and I just wished that people that loved it would stop trying to force me to read/watch more 'Potter stuff. Leave me be!
Troll and Troll 2, however...that's fantastic cinema.
