Just get the first Robocop, having all three you might be tempted to try watching the sequels. It'd just spoil it.
I haven't read the list too closely, but Fargo and Donnie Darko are both good.
Basically anything ending in "O".
Oh, and Teenage Mutant Ninja Turtles (but again, just the first one).
And the boxed sets of The Sopranos, most excellent.
