I honestly liked the first Chipmunk film, and it's allegory of new music talent getting abused by the record companies (if this was intentional or not). I'm mixed about the second. There's a lot to like in the second, and then there's a lot I felt was just the same lame tropes they shove into kid's movies to get 2 year olds to giggle. I didn't bother with the third, but saw some of it on cable at someone's house on Christmas... I wasn't exactly enjoying it, but (and this sums up my feeling about the whole film series and the poor casting choice of Dave) it took 3 movies for Dave to actually have fatherly feelings for his adoptive sons. In one sequence, they actually managed to humanize him, instead of having him grumble through a script for a pay check. Something he wouldn't bother to do in the second one.
