The Smurfs may be blue, but their movie is decidedly green, recycling discarded bits from other celluloid Happy Meals like Alvin and the Chipmunks, Garfield, and Hop into something half animated, half live action, and all careful studio calculation. The blueprint made bluer, but otherwise hardly altered has the chipper creatures invading New York City and replacing every third word with smurf, as in ''This smurf gets old fast.'' D+
