I have several, but whenever someone mentions guilty pleasures, Event Horizon is one of the first ones that pop into my head. While no masterpiece the film is incredibly well shot and made an impression on me when I was younger. And it's a lot of fun in a certain kind of way.
The Burbs!!! Yes! That is a hard one to find these days.
Some awesome choices here. Equilibrium... I need to watch that one again.
