I thought GTP would have had some amibtion to be an entertaining movie given the cast. But as it turns out the didn't use the potential. The lack in the script and of locations were covered by some slow paced scenes. That doesn't really support a the idea of a comedic road movie. And some strange choices ragarding the score made it difficult to connect to the 70ies rock'n'roll vibe. The movie felt so quiet most of the time.
Johnny Knoxville and Robert Foster dispointend (well the dialogues were badly written) - Christina Applegate as the psychotic girlfriend had the most bearable moments.
