If you (or your kids) really, really, REALLY like Shrek and friends then you'll probably want to splurge and buy this holiday DVD. Otherwise, just wait until it airs on TV again (which it presumably will) because it doesn't have a lot to offer in the way of content or extras.
It's a 22 minute Christmas special (which aired last year) in which Shrek, Fiona and his three little kiddies get ready to celebrate their first holiday together. But Shrek's never had Christmas and Donkey and Puss and Boots and everyone comes along to show him the true meaning of Christmas. Your basic straightforward heartwarming holiday tale... with ogres and mix breed donkey/dragon children flying all around instead of Sugar Plum Fairies.
There are some extras, but not very many. There is a "Deck the Halls Sing Along" and "12 Days of Christmas Sing Along", which feature edited sequences from the Madagascar penguins in A Christmas Caper, set to classic songs. Annoying, because things don't match up, the "12 Days of Christmas" lyrics have been changed from "three French hens" to "three wrapped fish," but they show a picture of four wrapped fish, and there are supposed to be "10 shoppers," instead of "10 lords-a-leaping," but there are only like eight. These things drive me crazy. My two-year-old didn't seem to mind. Though she wanted to know why there weren't any Shrek babies.
There's a game: Gingy's Dunking game. There are pictures of the Gingerbread Man with different faces and you have to find the match. Not challenging, for any age group. A trial of a Shrek Carnival game... which is not an extra. It's a commercial. And then the only feature that is actually worth anything, is the Dreamworks Animation Jukebox, which means that you can just watch the "Move It" scene from Madagascar and "I'm a Believer" from Shrek.
All in all, not really worth a full-price DVD. It won't even keep your kids busy for an hour. So if you feel that 18 bucks for a half hour's worth of entertainment is a good buy, go for it. You can buy it here.
