I would say the sci-fi/fantasy movies. My husband and I could watch the Fifth Element forever, We are also partial to Underworld Evolution and Blade, both vampire movies. Lord of the Rings the trilogy is another package that I could watch anytime. I've said it before the top three all time best movies, Princess Bride, Willow and Lady Hawke, We can also watch any day at anytime.

I never saw this movie so it will be great to see.
