This was a frustrating movie to me.
Christopher Waltz was fantastic as "The Jew Hunter" and all the praise he gets is deserved. He crafts a remarkably compelling villain, second only to Ralph Feinnes in terms of all-time great Nazi villains.
Tarantino also displays maturity as a filmmaker, mostly out of necessity, as he is unable to pepper lengthy amounts of dialogue with pop-culture references on account of the time period. The violence is also reigned in. He builds tension masterfully with entire scenes that are nothing more than two or more people having a discussion at a table. Good stuff.
That said, if he had reigned it entirely, and I'm talking about his irritating reliance on temp tracks (recycled not just from other films, but other Tarantino films), kitschy chapter titles and other Tarantino "homage" geekisms - we'd be talking about a great film.
As is, it's a good film that flirts with greatness, and that's what's so damn frustrating.
