Francis Ford Coppola hasn't heard a bad review yet at Cannes for Megalopolis, but that doesn't mean they don't exist.

Though it was the talk of the town at Cannes and received a 10-minute standing ovation, the Coppola-financed film received many good reviews and some that weren't so kind. The movie had its world premiere on Thursday, and from there, critics had their opinions over the Adam Driver, Giancarlo Esposito, and Jon Voight-starred epic.

The Wrap states that Coppola thinks all is good and hasn't heard any negative reaction from the film decades in the making.

“All I know is I came here, I showed the picture and I'm told it went over very well,” the famed director said. “Or maybe it didn't, I dunno. But that's what they told me.”

Well, reviews are mixed.

Currently, it has a 52% Tomatometer score on Rotten Tomatoes. Of course, that can change, but let's hear what critics are saying.

Critics' reviews of Megalopolis

Again, critics were diverse, with some good reactions, some bad, and some in between head-scratching.

Geoffrey Macnab of Independent UK gave the film three stars and said, “Megalopolis, Francis Ford Coppola's self-funded $120m epic, certainly isn't another Godfather or Apocalypse Now, but it's at least bursting with ideas…Ultimately, this isn't the car crash it could have been. It is, though, deeply flawed and very eccentric.”

BBC's critic Nicholas Barber gave it one star and said, “It's mind-blowing that Coppola sold part of his wine business to raise the money, and it's heartening that the 85-year-old maestro has finally completed the film after four decades of planning. In a way, it doesn't really matter whether Megalopolis is any good, or whether anyone ever sees it. What matters is that it exists. But the fact is that it isn't any good.”

He added, “It's like listening to someone tell you about the crazy dream they had last night — and they don't stop talking for well over two hours.”

TIME Magazine's Stephanie Zacharek said, “What does it all mean? It's clear that Coppola is feeling some anguish over the way certain honorable American ideals — essentially human ideals — have become distorted and warped, maybe even discarded altogether.”

There is some praise for the film, though some critics have an odd way of showing it.

Hoai-Tran Bui of Inverse said, “A bunch of ideas smashed together into a garish, baffling, dazzling, kind of atrocious, and totally audacious rejection of the cinematic form. It should never have been made. And yet, now that it has, we should be so grateful that it exists.”

Screen Rant's Brittany Witherspoon noted, “Megalopolis isn't just a transcendental delight for the senses; it's a manifestation of Coppola's dreams for humanity and his dedication to cinema.”

Francis Ford Coppola may not know that not all reviews are shining, but he'll surely pick up on this quickly. Meanwhile, the film is looking for distribution. Once it's released everywhere, hearing what audiences say about the mixed-reviewed movie will be interesting.
