Shutter Island is utter shit.
Hmm, Balaguero's The Nameless (1999 and for that not on the list) is much better than the disappointing Rec.
But then, most films on the list which I have seen (about half of the bunch) are good or pretty good.
Amongst the best are also The Ring (Verbinski), Eden Lake and the Dawn of the Dead remake by Zick-Zack Snyder. And Hostel 2, which is much better than the idiotic first one.
Oh, and All the Boys love Mandy Lane is fantastic. Probably the best, together with Anti-Christ.
Bukarest Fleisch is a small German one which is not very well known, not even in Germany.
