This is a silly movie that's also funny. With all the crap out there, why did it set a record for lowest opening day box office for a movie in 3,000 theaters? Perhaps it was simply not appropriately advertised. I see other reviewers using words like 'for teen girls' and for 'pre-teens.' I don't believe that those demographics were the actual target for this movie. A silly comedy with attractive teen girls starring in it also appeals to boys (although they might not be completely honest about it) and 17 is middle-aged teen, not pre-teen. Also, while there is no bad language in the movie that I noticed, there were definitely situations of a suggestive nature that I would not recommend for "pre-teens." I can't believe their other movies had this level of 'sophistication.' If you make a movie for older teens and young adults and movie-goers get the idea it's made for pre-teens, perhaps that is part of the disconnect that explains the box office failure.
My wife and I have no children, but really laughed out loud at parts of the movie, especially "the speech." I'm not saying who said what so this is not a spoiler. We have not seen other Olsen Twins movies, other than about 2 minutes in a Costco that had a special on their videos. Personally, I thought the girls were fine and the other stars solid. In fact, for my money, the worst actor in the movie by far was Jack Osbourne; not bad, just the least polished of the bunch. And yes, I have seen him in Ozzie Osbourne's family's reality show.
The bloopers, billed as "Hilarous Bloopers" were in fact pretty funny, especially watching the twins' reaction to each other's issues. Certainly, it might have helped to show those in the theater. As it happened, we rented the movie while on vacation. If you're looking for a change of pace from SciFi and Bourne-esqe thriller movies, you could do a lot worse.
