He gets called indulgent, like it's a bad thing. He makes films that he would like to see. What's wrong with that? Especially if you happen to love cinema, and the films that Tarantino homages.
With critics like yourselves, Tarantino can't win either way. If he was given a film to direct of a popular franchise, then you'd all call him a sellout.
If you can't understand Tarantino's mantra, then you have no place watching his films, nevermind offering your critique. Simple as that.
