Whether you enjoy this film or not is, in the large, down to you.
You could view it and believe the pace to be sluggish, the whole temperature of the film tepid and the plot over used and with nothing new to offer.
Admittedly if you want a fast pace and something grippping, this won't be your cup of tea. But you may enjoy it because, these actors have done a wonderful job. This film is subtle, it requires for you to have a little patience and understand this isn't meant to come across as a deeply over dramatised film, we're meant to see these characters as real. They've crafted their roles carefully, they're all flawed, like in reality, they are also, thank God, not all polished, perfectly dressed Hollywood Barbies. They are two good looking men, and their wives are different, yet attractive. Naomi in this role looks very different, she looks like a boring suburban mum.
If you look a little harder and think of these people and their struggle as real, you'll see beautiful acting, a subtlety that makes this film believable, a lovely score that brings out the films underlying sorrow and a script that shows the reality of adultery and marriage, without the frills.
A lovely film, if you're prepared to be patient.
