I loved Inglorious Basterds and I'm not that big a fan of most of Tarantino's other films, apart from Jackie Brown. The fact that this is a period film and in three different languages means that for once most of the characters didn't sound like they were talking with Tarantino's voice. I find a lot of self important prestige films that deal with the Holocaust directly (Sophie's Choice) or indirectly (The Reader) tremendously offensive. They often strike me as cynically engineered to grab awards and they ponderously exploit the Holocaust for cheap melodrama. Inglorious Basterds on the other was a joyfully irreverent take on WWII films (not on WWII itself). It's a wish fulfillment revenge fantasy, but it is only offensive if you mistake it as a film about history than a film that parodies and plays with genre conventions. In that way it's similar to The Life of Brian.
