I don't know why you people have to critique so harshly, it's not like they're shooting to make an Oscar award winning production here. They are aiming to entertain a group of girls in the age ranges of approximately 12-16 years of age who generally enjoy watching movies that talk about boys and fashion and going to exotic places. I'd say that if you asked pretty much any 12-16 year old girl that enjoys good old Mary-Kate and Ashley if they enjoyed this movie, they will probably say yes. And they will probably say yes if you asked them about the other ones as well (personally, I enjoyed passport to Paris, our lips are sealed, winning London, and holiday in the sun the best). You're all entitled to your own opinions of course but just take into consideration what the production people are aiming for, jeez
