Inglourious Basterds is written like this on purpose (he kinda explains it on Letterman ; google it).
I saw the movie yesterday and it really deserves all the praise it can get.
Like moviebob said, I went into the theater only having seen the teaser, not the final theatrical trailer (which is even more action-packed) but I was nonetheless expecting a kill-bill-esque nazi blood bath.
SPOILER-ish...sort of.
The beginning was surprisingly good, but action-free; I said to myself that it must be the build-up and the relentless action will soon ensue. Well it didn't, even though it could've, with characters that beg to be shown mercilessly cleaving nazis, like Spieglitz and the Jew-Bear, wich were only introduced, the audience not (really) seeing their nazi-killing-spree.
Albeit dissapointed in this regard, near the middle of the movie I got over it pretty fast, once I truly grapsed what an amazing job Tarantino had done with this movie ; script, camera-angles, the actors (most of them) are AMAZING, the atmosphere is unbelievable. I was actually nervous during the first act, and thought I've heard girls screaming outside the farmer's house, I was THAT tense.
Tarantino's shit-happens-Travolta-dies-on-the-crapper moment in this movie is also priceless. Great movie, great review, this movie ROCKS and Brad Pitt, 3rd movie in a row in which he is simply amazing. Bravo and 'grazie mille, paysano!'
