I gotta say, this was actually a really fun movie. I haven't seen many Scooby Doo movies in quite a while, so I decided to watch a few. Saw Zombie Island, thought it was pretty good, came to watch this one next literally just because you get to see Daphne and Velma in swimsuits and I'm a lecherous lil' shit like that. I was wonderfully surprised by some monsters that, while not original, are actually executed really well and feel like they mean business, as well as gorgeous animation (even with the 3D CGI vehicals!) and some of the funniest Scooby Doo dialogue I've ever hears. You can actually find out exactly what's going on a good few minutes before the gang does, and most likely will, and the twist is wonderfully silly. Might be a little scary for really young kids, but even without a boat load of adult jokes, I, as a guy in his late teens, thought it really stood up by itself even for my tastes! If you've got 7-11 year olds, watch it, even if you don't, watch it, it's really fun.
