I'd say I am a healthy example of a fan of this series.
I like alot of aspects, but I'm willing to accept that some bits are a bit lousy and that it's not for everyone.
I draw alot of fanart, but that's kinda a must for me, since I aspire to be an animator or possibly a character-designer, so I need to get in practice.
I find many of the songs really good fun, even putting them as MP3s on my player.
However, it doesn't get in the way of my other interests. I have other hobbies and interests, I get out and about, I do like other movies (Though most of them are either cartoon movies or Godzilla movies, there's not that much difference), and I still hang out with friends, and for the sake of my friendship, I do tend to keep my love of this franchise on the down-low when they're around. I may say that I think the original is one of my favourite films of all time, but that's about as far as I'll go.
So, I'd say I'm a pretty big fan of the series, but it's a healthy obsession.
