You ge the feeling that the cast was well laid out almost instantly. Newcomer Breckin Meyer and Jennifer Love Hewitt play Jon and Garfield's vet Liz respectively. Both do a good job considering the rather childish script that lay before them. Now, that having been said, I have a problem with their relationship. The comic strip that was originally penned by Jim Davis has Jon acting like a brash, almost obnoxious ladies man trying to woo Liz into a date while Liz would want nothing to do with him. The movie version, which was executive produced by the same Jim Davis, has them totally opposite. In the movie, Jim is quiet and shy with Liz trying to get him to ask her out. Eventually it works with Liz giving Jon the dog Odie to live with him. (Odie would have been better done as a CGI as well, in my opinion.) Buth without the chemistry between Jon and Liz, there really is no movie, so I suppose a little creative license is in order. The other HUGE problem I have with this movie is with Happy Chapman, the villainous bad guy in the film. One of the first words out of his mouth is the "D" word. Now, I don't have a big problem with profanity per se, but the script writers forgot that this was a children's movie to be watched by children. His "D" bomb was unnecessary and the writers should be ashamed of themselves for this faux pas.
Overall, it's a cute movie with lots of things for children to laugh about. Yeah, a lot of the movie, especially at the end is over the top, but it's harmless enough and enjoyable enough to give it a moderate "thumbs-up" if you will. Although I am somewhat grateful that I've not heard a word about a possible Garfield 2.
