It's pretty much the whole picture for a children's film. It just doesn't seem to have that wow factor that Toy Story or Wall-E has. The animation is obviously flawless, but it again doesn't have any spectacular details like the fur in Monsters Inc. It really is just a film that's good to put on for children to keep them quiet for a while.
They will engage with the characters - Probably the hamster the most, as he is the most endearing character in the film. And if you go out and buy it now you will get the most adorable toy hamster you have ever seen. Alternatively, you can probably buy one in a Disney store.
This isn't a long film, and it definitely doesn't drag at any part. I can see this as being one of those films you have on your shelf and watch every year or so. It's entertaining enough for its purpose. There have been better Pixar films though. If you enjoy Disney stories this is probably a perfect example, so do give it a go. You don't need to see it in 3D to get the full effect, it's perfectly fine on your normal televisions, and you don't need to wear any glasses!
The DVD also has the Pixar Short based around Rhino - The hamster. Disappointing, I must say. It's like a very short version of the film Bolt, but instead of Bolt being the super animal, it's the hamster. Not very creative or original at all. But then again, the story of the film is very original. You definitely wouldn't of seen a story like this one. So that makes it quite fun to see.
So, if you're bored and like Disney - Watch it. But you're not missing out on anything if you don't.
