Now, I know what you're thinking - other than The Sting 2 and Fletch Lives, sequels are never any good. And you're right, but this one makes the original look like a Preston Sturges classic. I won't even bother you with the details, because let's face it - your kids are going to want to watch it anyway. Over and over and over again. And that would be fine if this was sheer, dumb, harmless entertainment. But it's actually pretty mean-spirited and they continue to use the squeaky voices to cover up not-for-kids dialogue (a reference to pubic hair from the first movie comes to mind).
And, at the risk of spoiling anything, take a look at the sleeping arrangements in the last scene and you tell me how kid friendly it is.
The DVD is coming out soon - consider yourself warned.
