For a while, Once Upon a Time seems as if it's going to be nothing but a series of extended digressions. But it's shaped like a Western, and gets better, tighter, and more surprising as it moseys along…
-David Edelstein, New York Magazine/Vulture
It's as self-indulgent as Tarantino has ever been, but at the same time very much still at the top of his game. The only downside being constantly pulled away form a main storyline by knowing a major tragedy could happen at any time right next door. Rating: 4.5/5
-Bill Watters, Aggressive Comix
Meandering but deliberate, gorgeous and garrulous, it is very much the writer-director doing what he does so well, but in very familiar fashion. Which brings up the possibility that in making a movie about movie making, his real subject here is himself. Rating: 3/5
-Matthew Lickona, San Diego Reader
Frankly, I find the entire experience baffling, and any attempt to laugh off the Manson murders as sitcom fodder embarrassing. Rating: 2/4
