Parents need to know that this sci-fi movie contains some mild language like "bastard" and "goddamn," but otherwise has very little iffy content. That said, the movie is not oriented toward kids or teens.
Positive messages:Dale's friends help him despite sometimes not believing him. His buddies are all very supportive of him when he's going through a tough time. The movie supports the idea that sometimes crazy ideas are legit, and that taking chances on the possibility of a new discovery is a good thing.
Positive role models:The main characters are upstanding citizens except for one brief exception -- when Dale busts into the radio station and ties up the engineer so he can get on the air with an important message.
Violence:One comically tense chase scene. A man gets taken away in a police car. The main characters tie up the radio station engineer and commandeer the station briefly.
Language:Regular use of mild language like "goddamn," crap" and "damnit."
