Its hard to take a horror film seriously when the first "creature" appears and the first thought that goes through your head is "thats the keyboardist."
The story is nonsensical but the actings not so bad.
If you are expecting to see a lot of Lordi you will be dissapointed as each member of the band makes just a short token appearence to kill or terrorise one of the cast.
Mr Lordi makes his big appearence at the end but the horror of his bat wings unfurling is somewhat diminished by having seen it at the Eurovision song contest a couple of years ago.
