I do not own any copy of Donnie Darko. Those of you with experience with, and knowledge of, the various releases, what do you recommend I buy as my first and last copy? I have the Blu-Ray from the library, and I noticed the grainy picture quality. Whether or not it is intentional, if you think a different version makes for a better viewing experience, please let me know. I'd also like whichever version I choose to have the most/most insightful extras.
