As you would expect from Susan Sarandon, Sam Neill and Emily Blunt, the performances in this film are flawless and it's one I would certainly recommend, although for me, the twist at the end was a bit of an anti-climax and the film itself seems little 'rushed' in places.
I couldn't help but feel that the original screenplay was probably a lot longer and that a lot had been cut out, and as a result, the story itself sometimes seemed a little fragmented.
All in all though, definitely worth seeing, if only for the excellent performances.
