I don't understand why so many reviews are so low. I am talking about the DVD release, so I don't know about the 4 hour version, but I find the movie entertaining. It is a made for TV movie, so it didn't have a big budget for anything. I thought the characters were believable and the acting was OK. Some of the dialog was a little wooden, but mostly the acting was good- not great, but good. There were lots of errors, but I was still able to suspend disbelief enough to enjoy it. I didn't notice any mountains in the Texas scenes. I agree that the kid was annoying, he was my least favorite character. I liked the first part of the movie before the asteroids hit better than the aftermath.
