From a huge QT fan: this is a genuinely bad movie

Rating: 3/10 (21 September 2019)

Some context: I'm a gigantic Tarantino fan. I haven't been to a movie theatre in years, probably because Tarantino hasn't released a movie to theatres in years. While this was in maybe its second week of release, I got my ticket and checked out the IMDb rating.
It was 8.3.
Immediately after it was over, I had trouble offering my thoughts to my companion. I ultimately settled on, "I can't tell if this is just Tarantino's worst movie (which doesn't automatically make it bad) or a genuinely bad film in its own right."
I've since realized that, two weeks in, the 8.3 was artificially inflated by the fact that most people who had seen it by then were fanboys. Anecdotally, I've had two conversations with friends who were relieved to finally hear someone describe the movie as bad. I'll actually paste from a text from the one that was most explicit:
"...yeah, I left the theater a little miffed at best. I've actually lied to people and told them I loved it, when I really didn't. At all. It was really bad. And it feels good to say that."
Now that it's at 8.0, it is certainly moving in the right direction, but this would be at about a 5.0 with any other director's name attached to it.
Again, I will be really excited to see his next movie. But this one was a bigger quality deviation from a usually-excellent director than Buster Skraggs was for the Coens.
I wish I could be as declarative about the performances- at least one of them. But, while the pairing of DiCaprio and Pitt helps to make it really obvious how much more talented Pitt is, of the two. I can't say that DiCaprio's Performance was worse than the movie itself. But that should actually serve as an indication of how bad the movie was, more than anything else.
TLDR; I actually don't believe the other reviewers here. It's hard for me to believe that many people liked this movie. My sense is they're motivated by fandom, not trusting their real opinion, and (justifiably) being worried they'll sound like the odd one out.
