I was positively surprised. This was the first film ever where I didn't dislike Mila Kunis. Her raspy voice has deepened through the years, which has played a key part in annoying me before. Her character was absolutely wonderful, compared to the average chick-flicks out there, witty, fast-paced and well-written.
Justin Timberlake on the other hand... his character was surprisingly bland, although I'm not sure whether that's because he was the counterpart to Mila Kunis (seriously, he just doesn't have nearly enough character and charisma compared to her), or if just bad writing.
The plot was nothing new, if you've seen even a couple of mediocre chick-flicks, you already know exactly what's going to happen. The ending was almost painfully cheesy, what with it's several flash mob shots, the "big public place and he declares his love"-scene, with singing and dancing and run-of-the-mill banter.
I knew there's never going to be a romcom without the usual ending where they fall in love and end up together and hold hands until end credits roll and walk towards sunset over happily ever after, but even though in the dialogue they kept making jokes about romcoms and the cliche ending of boy getting the girl, I was disappointed that they decided to end the film in the way they kept mocking this whole time. If it was supposed to be satire, I didn't see any.
The real problem I have with these chick flicks, not this one specifically, is that they fuel the illusion of casual sex becoming a serious relationship. It's an illusion which in real life will not ever happen, or happens as often as winning the lottery, so virtually nonexistent. Chick flicks keep giving these pipe dreams to romantic girls and women who want to believe in something which at best is the fastest way to break your heart, at worst... One day you wake up in a shitty job, supporting two kids with different dads who're never there and still hope for the white knight to sweep you off your feet.
Newsflash: That will never happen. Stop substituting your own dreams with chick flicks. There's no magic that'll turn a hookup into a husband.
Also, this applies to women and men alike. If someone wants you only for a booty call, that is not love, and will not turn into love. Stop fooling yourself.
