SERIES PREMIERE: Rob Lowe is the host of this new Fox game show, which is part Jeopardy! played on speed dial, and part astronaut-training obstacle course. It’s weird, it’s fast, and Lowe may as well be playing his evil Number 2 henchman from the Austin Powers film – because he gets even more delight in the discomfort and anxiety of the contestants than Ellen DeGeneres does in NBC’s Ellen’s Game of Games. Is Mental Samurai fun to watch? You decide… And you’ll know before the first round is over.
