I had this movie on DVD as a little girl, and me and my sibling watched it all the time. When we watched it again as older teens, we were surprised at how well it held up.
Yes, the CGI is hilariously bad by modern standards, but for low budget CGI in 2004, I'm sure it could have looked worse. There is no excuse for those bug abominations, though, ew.
The movie is pretty funny, with some good visual gags, and the set design is also pretty nice.
I really like the messages of "making jokes when bad things happen is inappropriate" and "think before you speak", as I feel those are still very important things for kids to learn.
The songs are pretty hit-or-miss. The opening and the credits song are bad, but Funshine's two solos and the Joke-a-Lot group song all slap.
Overall, it didn't age quite as terribly as expected. I would recommend this to parents with young children, and maybe to adults too, just for a laugh.
