It was OK, my little brother seemed to enjoy it. It had some laughs, but it was dumb, stupid, no plot-line, but it was funny in parts, and had some good "stunts". 5 out of 10 or ** out of ****

I am heartened to see that, for a change, most others agree with me on the dopiness of this flick. Therefore I shall simply add that this has nothing to do with Yellowstone National Park. The "filmmakers" knew nothing about it but that Old Faithful is there and knew nothing about national parks but that rangers wear uniforms. I watched this to see how goofily unrealistic the geysers and hotsprings would look. Surprise, there aren't any, besides a spout of water in the background (Old Faithful) and a love scene in a hot-tub (the hidden hotspring). Disney couldn't even be bothered to make some plastic scenery! Yes, along with each other Hollywood film, they simply set everything in the studio's grassy fields with California's generic mountains in the background. The park's geology and animal-life are joyfully manipulated by the HEROES as the SOLUTIONS to the villain's evil actions. To the filmmakers, the only difference between commercial tourist attractions and national parks is that national park employees wear ranger uniforms. And these are the same people getting worked up over global warming? For sure. But any film with A J Langer is worth at least 3 stars.

This movie blew my mind. Seriously. I was watching it and about every 5 minutes Paul Walker would say something that would make my head feel like I was about to have an aneurysm. Do not watch this if you have any congenital heart defects. Or you will die. Or have diarrhea. Paul Walker is such a bad actor. Did you see that movie with Steve Zahn and that semi-truck? That semi-truck was the best actor in that movie and if he had been in this movie he would have been the best actor in this movie too. Only watch this movie if you have an IQ under 60. If you watch this movie with an IQ over 60, you will watch the credits with an IQ under 60. I can't do math anymore.
