“E.T.: The Extraterrestrial” was an unforgettable movie. It was heartwarming and it created a relationship between man and extraterrestrial that was, well, I guess…human. What “E.T.” didn’t have though, was an alien voiced by Seth Rogen, who usually plays a stoner-type. Combine that with a story written by Simon Pegg and Nick Frost, and a stellar comedy cast that includes Bill Hader, Jane Lynch, David Koechner, Jason Bateman, Kristen Wiigg, Joe Lo Truglio and Blythe Danner and you have “Paul,” a hilarious comedy about the relationship between man and man-child-type alien.
