I saw "Cheaper By the Dozen 2" on the plane flight from Japan. There were a few funny moments, and the movie was "cute". Eugene Levy is reliably funny, and Bonnie Hunt has that incredible combination of funny/sexy/HAWT that's all too rare today. Hell, even Hilary Duff was ok.
But Steve Martin...wow, how the mighty have fallen! I remember listening to Steve's stuff as a pre-teen, cracking up at his King Tut and Chzech immigrant routines on LP. Aside from The Jerk, his first few movies were pretty funny too. With Roxanne, he seemed to hit a new stride of witty/funny, and seemed to re-invigorate himself.
But watching his antics in CbtD2 just appalled me. His "acting" consisted of pop-eyed double-takes and ridiculously goofy gestures. Really, it was awful. I kept wondering why the hell Bonnie Hunt stayed married to a buffoon like him. Dreadful.
