The main characters in the cast were totally adorable, but it was kind of annoying when typical Disney made all the adults into stupid nut-cases who treat kids terribly. The plot was also fairly good, kids going back in time to save the geeks from embarrassment, but I think they got a little carried away towards the end with the black whole. When Charlie (the younger super-genius friend) ran into the FBI and suddenly exclaimed "four hours until the end of the world" I couldn't help but laugh, as it was just far too over-the-top. Overall the point of the movie was pretty cute though, accepting your past, learning popularity isn't everything, and loving your friends for who they are.
