Where was the 30 days of night?

Rating: 1/10 (15 May 2008)

Maybe I'm confused, The movie was called 30 days of night. In the movie they talked abot 30 days of night.
But it seems to me there was only 1 day of night.
Characters go in the attic locked themselves in then leave and kill the bad people.
Where they in there for 30 days? I don't think so.
1 day of night to kill off the bad people. Terrible movie nothing good but the way the bad people looked. Great look but terrible acting and story.
watch it and waste your time also.
