I'm in my early twenties, so by all accounts, I am not the target demographic for this movie. But I just watched it with my young cousin. First of all, the little dude loved it, so even if I'd hated it I couldn't give it a bad review. But the thing is, to my surprise I didn't hate it.
There are a few laughs there for older people that will probably fly over kids' heads, and the main character Harry is a former homicide detective from New York or somewhere which was pretty sweet. There are even a few light action scenes with Harry that were cool.
There are interesting actors in there too: Diana Tilden-Davis plays a hot park ranger. I looked her up and she was a beauty queen in Africa. Also, if you're a CARRIE fan, William Katt has a pretty big role as a plane flying priest.
The most important review though, and the reason I'm writing this, is that my little cousin loved the thing, and if you can entertain an eight year old for an hour and a half you're doing all right!
