OK, I'll be honest here: I always thought Darth Vader was the coolest character in Star Wars.
Cooler even than the smooth Han Solo and waaaaaaay cooler than Luke Skywalker.
And that was before he became a reformed man in Return of the Jedi.
When I saw the first film (Episode IV - A New Hope), I tried using the Force - I was only seven! - but to no avail.
