Full of fashion (lots more than the show, great!), extension of characters, ups and downs, this is definitely a chick flick but guys who are familiar with the characters will love it as well.
I like the lead guy from When I Met Your Mother, and it was good to see the girl from That 70's Show, but really this movie dragged so much between fun parts, it wasn't great. Pretty juvenile jokes, which I'm certainly not above, but they were inserted into lines/action that would just plateau every once in a while and make you realise you're sitting in a movie theatre - kinda like a record that keeps skipping.
