That old chestnut...
If you actually look at the violent moments in most of Tarantino's movies, there are actually very few violent moments in them, though the ones that are there tend to be highlighted, celebrated and discussed endlessly by the media.
Take Reservoir Dogs...it's an intensely dialogue-heavy movie. As is Jackie Brown, Pulp Fiction and Inglorious BasterRAB.
And for me, the best two scenes in that movie are the opening sequence with Christophe Waltz, and the scene with the German soldiers in the tavern...both very long, dialogue heavy scenes, but yet intense and gripping.
Some people always seem to forget that Tarantino's movies are primarily dialogue driven, and always seem to be looking for shock moments and 'cool bits'.
And they just don't listen to the dialogue, hence they come away with the impression that the movie is boring and nothing happens.
I guess good, well-written dialogue in movies is just not your thing...you should probably stick to Michael Bay movies and other such big, dumb action movies.
