I had a night in dog sitting last night whilst my sister was in hospital so I watched a few films to pass the time:
Black Sheep
This is an extremely tongue in cheek dark comedy, you couldn't really call it a horror film, about a flock of infected sheep on a New Zealand farm that go on the warpath. It very much reminded me of Brain Dead with a bit of Shaun Of The Dead or An American Werewolf In London thrown in. It's 1 of those films that doesn't really serve a purpose, it's just something to laugh at for 90minutes :D It's immensely stupid and cheesy but it kept me amused when I wasn't in a mood for anything too serious.
I did also have Requiem For A Dream to watch as well but thought it might be a bit deep for the mood I was in.
Switchblade Romance/High Tension/Haute tension
This starts out as kind of a home invasion type of film but then moves out of it about halfway through into a story of 2 girls who are trying to survive the night after being taken hostage by a killer who murders the family of 1 of the girls and then takes the other hostage, leaving her friend to try to rescue her. It's a fair bit gorier than I was expecting, not an issue but worth mentioning, and it seems to trade substance for tension, which it seems to do well.
