Fun enough, and probably an amusing watch for fans of the original (which I am), but not really anything special. The first one broke new ground, and this gets bigger and badder in the best tradition of sophomore sequels but doesn't really bring much new to the table beyond that. The sole exception to that is one notable and long stunt sequence, in which teeny-tiny gamine Chloe Grace Moretz takes out a whole van full of bad guys from on top of, alongside, and finally inside it as it speeds down the highway. That was cool.
