There are two versions: the 167 minute version without an intermission which will be projected digitally (as most movies are today) while select screenings are the Roadshow version, which is 182 minutes, plus an intermission, all through a 70mm film projector (the biggest, brightest, best, and most expensive kind of film), the kind they used to make epics like "Lawrence of Arabia" and "2001: A Space Odyssey" on.
I saw the Roadshow version a few days ago. You didn't hear it from me, but the other version is available on torrent sites in that unprecedented leaking of awards screeners this past week.
I was never bored by the movie, yet I can't tell you that it's anything more than what it's about onscreen, which is basically a Tarantino murder-mystery, a western, and an exploitation movie all mashed up and set in post-Civil War America. I'm sure partisans will bring whatever message to the movie they think is there, but I must admit, I don't think this movie has a message. I don't think it's his best, but I wouldn't call it a stinker, either.
