DreamWorks Animation mashes together E.T. the Extra-Terrestrial and Lilo & Stitch in the hopes that wayward alien mascot Oh (voiced by Jim Parsons from "The Big Bang Theory") will become the next toy/video game/t-shirt-generating machine. It's safe to say he won't. The story, about a misfit alien who befriends a lonely Earth girl (Rihanna), feels awfully recycled. If you're an adult who doesn't find Parsons' voice grating, you might survive a screening with your kids.94 minutes PG.
