After the first 30 minutes I felt like the film lacked energy. The pace was a little too slow for my taste, and the intensity too low. I wanted it to be snappier, more sizzling.
But then, about halfway through, it got really interesting. The second half, although it still suffers from some pacing problems, makes up for the first. And then the third act is one of the most brilliant and satisfying third acts I saw in a long time. The ending brings together all of the elements and themes that were planted throughout the movie (our obsession with the way things look, the line between art and real life) to form insights about our lives that are as brutal as they are true.
I am generally fond of Neil LaBute's work - most of the time his works contain more than what they initially seem to be (I haven't see "The Wicker Man" remake yet, but I heard it was horrible). Here, what starts off as your run-of-the-mill romantic comedy/drama, develops into a cynic's paradise, presenting insights into our lives which are as brutal as they are true.
Three of the four actors do a splendid job (Weisz, Rudd & Mol). I especially liked Paul Rudd's performance, and the way his character changes throughout. All three, and especially Rachel Weisz, are convincing in their roles, and deliver multi-layered performances with lots of subtext. Fred Weller's performance leaves something to be desired, but the fact that his role is well written somewhat makes up for that. LaBute has successfully made all four characters three-dimensional and they feel like real people.
Overall, I'd say it was a pretty great movie, certainly entertaining, and an important one to watch and analyze if you are into writing, directing or acting. Somewher, though, I feel like it didn't live up to its full potential. This script, if directed with more intensity, could have become one of my favorite movies, up there with films such as "Closer", "Glengary Glen Ross" or "Oleanna". Maybe it's the transition from the stage to the screen that made LaBute feel like he should make everything more minimalistic and restrained. But it's definitely worth checking out.
