The sitcom is back with new episodes, as Ted and Barney celebrate St. Patrick's Day. Which pleases me intensely. Here’s what doesn't please me intensely: The guest-starring visit by Britney Spears that will be in the third new episode in two weeks. I really don't want to be thinking about what Spears is doing to her children, or what our culture is doing to Spears, while watching my favorite traditional comedy. I don't want to be thinking about real mental institutions and Barney’s "hot-crazy scale" at the same time.

This comedy is a showcase for Michael Keaton with a simple and appealing premise. He's too busy to be worker, husband (of Andie MacDowell) and dad, so he has himself cloned - and then has to deal with the pitfalls and the personality differences among his replicants, a challenge that shows off Keaton's acting skills. (PG-13; runs through March 31)
