I liked the bit when Luke says "You've got black goo on you".
And also when he tried to pet a hissing monster when he should have roared right back at it.
In all seriousness though this is a great horror flick, British in nature, set in Northern Sweden and full of good quality movie moments and a sizeable amount of horror (Of the scary variety).
I'd recommend it and would say a 7/10 and, for a horror film, that's a decent score indeed!).
