Maybe I have a pickle up my ass, but I never even cracked smiled once during this movie. I like science fiction comedies (GALAXY QUEST, SPACEBALLS, etc.), but PAUL was a complete dud. Fucking FLIGHT OF THE NAVIGATOR was funnier than this abortion. "Compliance!"
The story is about two sci-fi nerds who are on a road trip checking out different UFO tourist attractions when they witness a car wreck out on a desolate desert highway. At the crash site they find Paul. Paul is an alien who's on the run from the government, so the two nerds decide to help him get to a location where an alien spaceship can pick him up. Many different alien anal probe and alien testicles comments later the film ends and I sat there in complete amazement that somebody could write a "comedy" script so lame and actually get it made!
I watched this alone, so I can't comment on what other people think, but I have no idea what anybody could even find funny about this movie. Was there even one joke? Maybe it was all nerd in-jokes that went right over my head. Whatever. I found it completely weak, with too much drama bullshit going on for my comedic tastes.
Skip it and never look back.
