A Movie that would have been a great TV series.

In my opinion I Am Legend would have been a good one if done right.

Interview with the Vampire...and the rest of the Vampire Chronicles. It could show tv shows like True Blood and Vampire Diaries how vampire fiction can be done right.

Thomas Jane's "The Punisher"

Back to the Future

Terminator

oh wait, it was :)

Harry Potter

Star Wars.
