It was great to find this collection in DVD format - it incorporates 'Where the Wild Things Are', 'In the Night Kitchen' and 'The Nutshell Kids'. It is suitable for all ages, if your child loves the book, they will love this! It uses the original text, too, so you can join in.
For those of you who, like me, grew up in the 70's, this has a wonderfully nostaligic feel. 'In The Night Kitchen' (featuring an animated Laurel and Hardy) has a surreal, dreamlike quality, which is slightly disturbing, but Hey! Kids love it! (mine does, anyway...) 'The Nutshell Kids' is set to music, sung by Carole King.
If you are expecting a slick production, you will be disappointed; this is a basic animation using Sendak's original illustrations. It's lack of polish adds to it's charm, though.
The only disappointment with this particular DVD edition (I don't know if there are any others), is that it's not possible to dip in and out of 'The Nutshell Kids', there seems to be no 'scene selection' option.
Apart from that, I thoroughly recommend it.
