I concur with Vintage's views, although I did watch the PT several times on DVD, twice with my kids.
And it's not that subjective when it comes to terms of epic/classic quality in movie history. The PT is not up there with the greats, no one but us geeks talk about it and if it's not hailed as a particular great movie, it will never be like that.
And I also doubt it'll end up in the great-cults-scene, like Blade Runner and films like that. It just lacks that extra thing, it's too commercial and too slick to receive such a support.
So in all fairness, the PT failed to impress the world as the OT did. And that is saying a lot.
