Friends With Benefits
Dylan (Justin Timberlake) and Jamie (Mila Kunis) think it's going to be easy to add the simple act of sex to their friendship, despite what Hollywood romantic comedies would have them believe. They soon discover however that getting physical really does always lead to complications.
I really liked this movie. It's easily the best romantic comedy of the summer - although it's definitely a rated R movie. It has more than enough laughs. Most importantly, the chemistry between Timberlake and Kunis was awesome and they played off of each other so well. They were both flawed and you totally understand why and root for both of them because they are perfect for each other.
I would definitely recommend people checking this one out. Again - it's a legit rated R but it is a great romantic comedy for adults.
