“Hopscotch” is an appealing but lousy movie. It looks like pea soup, the script is dull, and the acting is forgettable (I’m talking to you, Ned Beatty). But I’m a sucker for Matthau and Glenda Jackson so I sat through the whole thing, curled up on the couch with my wife over the weekend. Sometimes, it doesn’t matter that a movie is bad. If you are cozy with the Mrs watching Matthau humming Mozart, sipping beers, being Matthau, things could be a lot worse.
