I just got done watching The Edge of Love (by the way, this is one of the worst titles so far this year) and it felt like a chore. Watching Keira Knightly's unlikable, skeleton-looking character made me cringe even more throughout the coarse of the film.
It took me four nights to watch this it was so boring. The only good thing about it was Cillian Murphy. He's always good/believable and is severely under looked in many films. This, however, was just not good enough for him.
Apart from the unlikable characters, boring storyline, the plot was also emotionally unsatisfying. I felt like I spent my time watching this for nothing (which I did). I should have done the smart thing and turned it off, but I kept it on out of respect for Cillian Murphy and the great cinematography.
