Saw it last night in 70 mm. Overall, I liked it, but this was not QT's best work. I would rank it clearly behind RD, PF, IB and DU, and not clearly ahead of his other movies.
IMO, one of the best things about QT is his character dialogue. For example, conversations between Travolta and Jackson in PF...many of those lines are classic and unforgettable. Similarly, Harvey Keitel and Steve Buscemi had some extremely well written dialogue in RD. There are a lot of examples of what I am referring to in all of his movies. In this one, there was a little bit, but very little. There were times that I could tell he was trying to go in that direction, but it just felt forced and fell short of the mark. Part of the problem may have had to do with bad acting. I felt like Kurt Russell was a caricature throughout the movie. Walt Goggins and Samuel L. Jackson had good and bad moments. Madsen is not a good actor, IMO. I thought JJL, Tim Robbins, Dern, and the guy who played "Bob", were great throughout the movie.
One thing that I am confused about....Who are the "Hateful Eight"? Throughout the majority of the film, there were 9 people in the cantina.
1). Kurt Russell
2) Jackson
3) Dern
4) JJL
5). Tim Robbins
6) Madsen
7) "Bob"
8) Goggins
9) "O.B." (the stage-coach driver)
Other characters are in the movie (I am purposely trying to avoid spoilers here) who could be considered "Hateful", but it is a bit ambiguous. My guess is that "O.B." is considered a completely benign character and is not hateful, but I don't think it is completely clear who the "Eight" are (especially because there is 1 more character who should be labeled as "hateful").
I am probably coming across as overly critical. I really did enjoy the movie and will probably watch it again at some point. It was a fun ride for sure. I really liked what was done with the narration coming right out of the intermission. Different, but clever. I also thought the piano scene was really well done. In an above post, MJD mentioned over the top blood and guts. I really didn't think it was that bad. I feel like Django, Inglorious Bastards and Kill Bill were significantly worse, in that regard. I would probably include the ear scene in RD also.
