The first half works as a look at the claustrophobic world of someone caring for a mentally ill relative, thanks to Jennie Stoller's performance as Sandra. David McAlister, known to the hung-over masses as Dennis Richardson from Hollyoaks, brings a decent level of menace to the volatile Norman, until dodgy sound effects of dogs barking and children singing are used to illustrate his mental distress, the melodrama is over-cranked, and it turns into Tales Of The Unexpected.
