Ok, whilst I consider myself a bit of a horror connoisseur, I like all different aspects, so I can go from c-grade trash to a-grade terror depending on my mood... here's my top tips:
Eraserhead - Arthouse, psych-fest, I don't know why this movie scares me, it's one of the few things that makes me feel ill, really nauseous.
Soundtrack is unrelenting and there's some very disturbing imagery, it's like watching a nightmare.
Severance - Like Shaun of the Dead, but good. It's pretty brutal and there's a lot of humour in it, but no jokes, just natural humour, some of the
characters do and say funny things, but it doesn't come across like joke-setups. Really worth watching.
Mum & Dad - Newish Brit/flick, seriously nasty, unrelenting and some of the best dialogue I've ever heard, these people could be your neighbours.
Man Bites Dog - If you're good with subtitles, this is great - a Belgian film crew follow a serial killer around whilst making a documentary.
There's at least five scenes in this film you'll hate yourself for laughing at. Beautifully shot as well.
The Cube - Great low budget psychological horror, could well be interesting for ATSers.
If you only see one of these, see Mum & Dad, it's my favourite this month.
Some of the previous stuff mentioned that I really rate includes: Bad Boy Bubby, Wolf Creek, Bad Taste (anyone mention Brain Dead?), American Werewolf
In London and Ginger Snaps is really good too.
