What film should I watch?

I've decided I'm going to raid my house for DVD's and watch a movie
that I've never watched and never would have considered watching.
I found these;
The Dark Knight
Grim Reaper - kinda like final destination?
Equilibrium
House on Haunted Hill
Perfect Storm
Planet of the Apes
One Flew Over The Cuckoo's Nest
Stigmata
The Howling (it's a sequel don't know which one)
As i said, these aren't the kinda films i saw and though "omg, i must
watch that!" instantly.
I'll watch anything as long as it's not boring, complicated, too
sci-fi-ish or too much gross-out humour. I wanted to watch The Dark
Knight, but I've never watched Batman in my life and I've never been
interested in it. Could I still watch it and actually understand it?
Which of these should I watch, in your opinion?
i meant from the list.
