Been a while since this was released, but I'll be honest, this was far better than any DVD I've seen of the film. Yes, there's grain, but at least they didn't try to erase it and erase some of the detail of the film with it.

: Look at the rocks or the paintings of the earth....a lot of that detail would be gone if they tried to digitally scrub this movie clean of film grain. I'm glad they didn't.
Extras...well, this wasn't exactly Disney, and home video basically was just around...to watch the movie, not watch extras, so I'm not surprised there's no bonus content. You can find much more online from printed media of the time where you would actually read and hear about this stuff.
I've shared my opinion on this multiple times on that blu-ray.com forum thread. I post as CharlieBarkin over there.
