The acting was the only thing going for it really. You're not wrong, the story was a complete snooze-fest. I'm not exactly a big Tarantino fan but I did appreciate the stories in Kill Bill, Inglorious Basterds and Pulp Fiction. As far as I can remember, up until Foxx and Waltz arrive at DiCaprio's manor (where the story really begins) they're just trekking boringly through rural USA with the odd unnecessary monologue and lynching/shoot out to boot.
I hate that Tarantino doesn't like to make his movies believable to the audience. Samuel L. Jackson's character speaks like he grew up in 20th century New York - did words like 'motherfucker' even exist then? After all that goes on, another shootout with stock standard Tarantino violence, the girl dies and the story should effectively be over, right? Because as far as I'm aware the story is about Django and his love for whatsherface. The drawn out, stupid and irrelevant ending pissed me off. Why the fuck has Tarantino's character got an Australian accent??!! The Australian accent barely developed into what we hear in Django until the 1960's. The ending contributes nothing and it goes for like 10 minutes.
All in all the film was boring and the story didn't flow well one bit. Its a really shallow way to make a movie to have next to no story and accompany it with 'cool' Tarantinoisms - meaning things that don't contribute anything to the actual story they just look and sound cool or different. I thought it was an abhorrent excuse for a movie and hearing everyone talk about how good it is was bloody torture.
