The cast is different but it does Star Natasia Demetriou (Sophie) with her real life brother Jamie Demetriou. Both series have charm and are funny in unique ways.
I would say it's way better than the movie. I thought the premise of the movie was funny but I didn't find the movie itself very funny. No, that's not right, I thought the movie kind of sucked. The first 30 minutes were amusing because of the idea but not because of the antics.
The TV show on the other hand, I will laugh out loud at least once during an episode which is rare for me.
They have a much more engaging set of characters whose antics keep you entertained. The premise of the movie seemed to float the movie to its end but the TV show gives you new insight into the characters and their issues each episode so it has a 'new' feeling each episode. And a couple guest appearances along the way.
