At the time of it's release Jackie Brown was a misunderstood film that people didn't expect as a follow up to to his masterpiece, Pulp Fiction. It's a completely different type of movie and was the first time that Tarantino strayed into making a film from pre-existing material. While it's not as great as it's predecessor, it's still a good movie with a strong plot and equally distinct characters. The public at large expected another grandiose inter-weaving of stories. Tarantino went the opposite way and developed a more typical film based on an Elmore Leonard story.
While the film still holds up well, it did not receive the royal treatment for the blu-ray release. Although I'm a fan of grain in any format, this disc has way too much and is not a far stretch from being a DVD quality release. Not enough time was spent remastering this for the blu-ray format. This was quite disappointing.
If you've never seen the film, I would suggest seeing it for the sheer fact that it has the Tarantino mark. But, do not expect something as good as Reservoir Dogs, Pulp Fiction, or Inglourious Basterds.
