I wanted to see this movie when it came out, finally got the chance renting it. The story is pretty complicated to explain, it's one about a girl named Coraline who has moved into a new house with her family and meets with a ton of colorful to say the least characters in her neighborhood. She manages to enter a world where she meets her Other Mother who she prefers at first but begins to learn about the scary secrets she holds. Storytelling wise, this is probably the best medium between Pan's Labyrinth and Disney's Alice in Wonderland to date, there's appeal for kids and adults, and it's a pretty complicated film with a story to ponder on. Of course if the imagery doesn't look like it will keep you from getting unpleasant dreams at night, then that's pretty much the only reason I can see there not being much appeal.
