I enjoyed that and I'm pleased she's produced something decent. I agree with @littlepup though - everyone was pretty horrible so I didn't care what happened really. That scene when the dead guy is upstairs shagging his gf loudly in someone else's house then he comes down and shags Daisy's character in the utility room with her son outside listening is grim.
It's clearly got semi-autobiographical elements. I do feel a bit sorry for her ex-husband.
