Why this one could be better...
The man can make a sequel!
He directed both Scooby-Doo movies. The first one was kind of dull and insignificant, much like the first Smurfs movie...however, with Scooby-Doo 2, he seemed to learn from the mistakes and gave one of the best cartoon-to-movie films out there today.
This is just a mild comparison, I realize...but if he improves the Smurfs even a fraction of the amount that he did with Scooby-Doo, than I am sure that it will be better...cause face it...it surely can't get much worse.
