Circuit City had the HD version of 300 playing on one of their widescreen TV's, this evening... I stopped long enough to confirm for myself that the detail of the HD pretty much puts the DVD to shame. I still don't see myself upgrading any of my DVD's for a very long time, though... I can't imagine a lot of my movies actually improving in terms of transfer, besides films that I really obsess over (Star Wars, Indiana Jones, Jaws, etc).
Really, do I need Ernest Goes To Jail in HD format?
