I'm not hating on the movie. I just think it looks lame. And true, I am not the target audience, although it has always been my belief that children's media can have appeal to adults as well and doesn't need to be dumbed down just because you're targeting a younger audience. But alas, there is kids' media out there that does indeed feel "dumbed down" at times.
Although I will acknowledge that this is merely a trailer, and the final movie could in fact end up being really good. But either way, I just don't think this one would be my cup of tea. Or if I can put it another way, the trailer at least just didn't win me over.
