I like them all, especially 1 and 6. However, if I were to choose, it would have to be 6. :) The fact it's set in Alaska made me think of the 30 Days of Night movie. If you need a plotline, there's a good one for you. It's horrific, fairly gory, and hey! For monsters, it's like having a big ol' packed lunch, what with everyone locked inside one building. :D
