I'm not usually a fan of Disney films, but I can certainly spot a good one when I see one. Sadly, The Incredibles doesn't fall into that category. I saw this at a packed out cinema and it certainly has its moments. The story is the standard sensationalist superhero stuff and it does appeal to adults. It results in plenty of comedic scenes that had most of the cinema laughing, though that's really all I can remember of it. I think it's entirely appropriate for children, but I wasn't exactly swept off of my feet in the same way that I was with Toy Story, for instance.
It's definitely a children's film, there's no reason for adults to undergo 'Harry Potter' syndrome and pretend it's anything more! The most intriguing aspect of the film for me was Holly Hunter's voice acting. There's just something great about her voice!
