'The Smurfs 2': Better than original, but too true-blue for adult viewers

Midway through Raja Gosnell's marginally acceptable "Smurfs" sequel, Grumpy Smurf turns over a new leaf. Sick of being annoyed (and of annoying others), the irritated Smurf starts to view the world -- and the current mission involving his pint-size friends -- through rose-colored glasses. He even adopts the nickname Positive Smurf. Suddenly, things don't seem half bad.
