If anybody had seen sense the first time around, we could have been spared those two live-action atrocities. Finally someone semi-sane realized that all-animated and based on the comics is the way to go.
On the other hand, it is still quite likely to suck, as it comes from the director of Gnomeo & Juliet (because little guys with hats, amirite?) and Shrek 2.
Nobody stopped to consider that maybe NO Smurf movies at all were needed, because that's just crazy talk.
