'Garfield on the Town' was my favourite Garfield film. I saw it when I was very young, and I always felt very sad when Garfield goes back to the place where he was brought up as a kitten, and he remembers everything about this place (and his mother) and recalls how it used to be and how it has now changed. It's a very emotional scene, and you really do get to see another side to Garfield beyond the funny comments and the laid-back attitude.
I don't think the film had too much more to offer, sadly, than this scene. At least, the rest of it is not very memorable. I first saw this when I was about five-years-old - when it was first on television. I saw it a few years after that, and besides the scene where Garfield visits his old place, I don't think it had much more to offer.
I cannot say whether or not I recommend it. I can just state that I did enjoy it, and it was a very memorable film to me.
