Paul the alien is a pot smoking lazy ET on the run. He meets up with to brits and the journey begins. I can say Seth Rogan was great as Paul. I have to admit, I can't find a movie Simon Pegg is not good in. Jason Bateman is great as a man in black. I laughed lightly during the movie and even though the plot was predictable, it was a good one time thing.
Paul is also responsible for most of the pop culture for the last 65 years.
