It may be targeted at early-teen girls, but I rented Penelope this weekend and it was actually really good.
The movie follows the typical romantic comedy path: boy meets girl, something interferes, girl meets other boy, shocking twist, right boy and girl get together.
Penelope came together really well though. All of the actors and actresses did excellent jobs (it says something when Reese Witherspoon isn't the cutest little pixie in a movie) and the story comes together nicely.
I give it two thumbs up, it's a movie I'd let my daughter watch.*
*Wow, I'm at that point already?
