I loved the movie, 9.5/10. And as everbodyies been saying, Christoph Waltz was fantastic. Only minor problem was the Basterds werent in enough of it.
As for imdb ratings, they flip flop so much. I remember when public enemies came out, the first round of very positive reviews came in, and it trumped the Godfathers 9.1 with about a 9.3 for about 5 hours, and about a day later it was down to 7.9
As for Inglorious Basterds, thats still up there, high on the list.
