First Impressions:
My first impression of the forum okay. You do have a pretty original forum, which I will talk about more in the next section. But what I am not liking is the dark "theme" you have. The "theme" does kind of go along with the niche` of the forum (and that's a good thing) but that isn't what concerns me. There has been a big debate for a long time about which is better......a light "theme" or a dark "theme". Sometimes the niche` of the forum can influence which would be better but I think either would be fine on yours. A lot of forum owners will have at least 2 "themes" on their forum, one light "theme" and one dark "theme". That way, their members will have a choice as to which one they want to use. I'm not saying you should be like everyone else but it might not hurt in your case to have a second "theme" that will be lighter than the one you are using now. That way everyone who comes to visit your site will be happy, regardless of which side of the debate they are on.
Average
Originality:
Well, I can assure you that I've never come across a site dedicated to the Lion King before so your site is pretty original as far as I am concerned. I like the fact that you have a section to discuss the movies but you've also give your members a section to discuss things like fan fiction and fan art. That is good. That allows your members to still enjoy the Lion King franchise while indulging their creativity. I would take the "shoutbox" down (at least for now). I don't suggest that new forums have those on there as it could take away from the discussions on the forum. Once the forum gets going, then you can probably add that back (as long as it doesn't hinder the activity on the forum).
Good
Thing you liked best about forum: You let members indulge their creative side.
Thing you liked least about forum: Add a second "theme" that is lighter than the one you're currently using.
Overall Mark:
I like you're forum, I really do. I'm a fan of a lot of the stuff that Disney has done over the years and this is one of them. I would make sure that you continually add content to the forum to help peek the interest of guests and keep members coming back. If you do that, it'll greatly help out your forum.
