Ill see your "They Live" and raise you "The Adventures of Buckaroo Banzai Across the 8th Dimension"
That's on OnDemand. I must've tried to watch that movie three times already and I just can't get into it. It seems to start off so slow that I just can't seem to get myself past a certain point.
Besides the ones already mentioned:
I've always had guilty pleasures watching
Beetlejuice
Spaceballs (Barf!!!)
Uncle Buck
Night of the Comet (SciFi Ch tried to make a remake of this one)
Doctor Detroit
Maximum Overdrive (Don't know why I love this one so much.)
The Princess Bride
Howard the Duck (It's so cheesy)
Tremors (Miss the TV show
)
check out
