Well, I think the ability to see the entire room by using the super 70 format really was a plus with this film. It definitely adds to the atmosphere.
Overall though, it felt like a lesser Tarantino entry for me. I felt it was covering similar ground as Reservoir Dogs, but less effectively. The film is certainly way, waaaaay too long. A lot of the actors seem to be playing things on completely different levels. Walton Goggins, Kurt Russell, and Tim Roth are really hamming it up, which doesn't match with the more subdued, realistic performances of many of the other actors. Samuel L Jackson is absolutely fantastic though, and any time he's talking or doing something the movie is electric.
It's worth seeing for the photography and the moments that work, but overall, not my favorite, and a marked step down after Inglorious Basterds and Django.
