This is the 3rd in the continuing Smurfs franchise.  The major difference is that the evil wizard Gargamel in this movie unlike the last 2 is animated.  I preferred the live action Hank Azaria as Gargamel (he's just about the best with comedic and evil timing) vs. the animated Smurfs. Now everyone is animated. Animation is good. 

Story is that there's a lost village through the forbidden forest that has other smurfs that don't know about each other. Our heroes including Smurfette have to rescue them because Garamel knows where they are and wants to turn them into a ball of energy for his magic.  Here's the thing, Smurfs are all male creatures except Smurfette (created from clay by Gargamel to infiltrate them) But the lost village is all female smurfs.  So you know where it's going to go in Smurfs 4.  Mate, procreate and live happily ever after. We're not there yet, in this one they all go to their first unisex dance at the end.  Set up for a sequel already. Smurfs are always fun, not a deep script but nice animation and the kids will like it.  Marc Coppola 2 stars.
