[quote name='Demolition Man']Which version of Donnie Darko should I watch... the original cut or the directors cut?[/quote]
Like Eviltude said, there isn't much difference. I think I probably enjoyed the director's cut more. I watched the original first though, so I would recommend watching both, but starting with the original. However, if seeing both versions doesn't matter to you, you might as well just watch the director's cut.
