It's waaaaaayyy better than Deathproof, Deathproof is easier to follow cuz it's a more simple film, this has a lot of storylines running which later connect to the plot in a major way.
The thing with this movie is its made for film buffs from QT's era of film surrounding the lore and legends of Hollywood. So to a lot of people not familiar with that, the movie might go over their heads.
Like Steve McQueen at the Playboy Mansion, Rick Dalton (based on Burt Reynolds career btw), Cliff Booth (Tom Laughlin aka Billy Jack) and others. It's a homage to the golden age of Hollywood so if you're not familiar with some of that the movie or the conspiracies surrounding the Manson family then it might be tough to appreciate like you do Quentin Tarantino's other works.
