Y'know, it's kind of sad to see some of the comments bemoaning Eddie Murphy for not swearing enough anymore. It's almost as if some people equate foul language with humour. If you're one of those people who thinks a comic sketch is much funnier with swearing in it, then you'll no doubt not like Eddie in this movie.
On the whole, I found DDC to be harmless, unpretentious entertainment aimed at kids, naturally, but with sufficient adult-only gags thrown in to keep the parents happy. In short, a formulaic kids movie designed to keep parents from being bored and kids amused.
The plot is silly, and predictable, but you don't go to these sorts of films looking for deep and meaningful dialogue or witty social commentary. You just go to be entertained. And DDC does deliver on that score.
Of particular amusement is Steve Zahn, as the rather cliched Star Trek geek who is the only one who can speak to one of kids - in Klingon! He does kind of steal a lot of the scenes in which he's in. Anjelica Huston is starting to look real old, but still has that menacing screen presence that no doubt helped land her the role of Mrs Harridan (yep, that really is her name) in this picture. I'm thinking she would have made a much better Cruella de Ville than Glen Close's overacting scenery munching version in 101 Dalmations.
The only thing I found a little irritating about this movie was the number of times a microphone popped into view at the top of the screen. I must have counted at least five instances. I kind of grew used to this in the 80's straight-to-video days, but you don't really expect to see it nowadays, so it was a little annoying.
Other than that, the movie is harmless and fun. And for those that complain about Eddie not swearing enough....this is a KIDS film, you know.
