A common theme throughout most of the critic and amateur reviews of Opus is that, "we've seen this before." The premise - an unassuming person enters a secretive compound/community that hides nefarious things - is pretty well trodden ground. The structure, where, just by the trailers you can tell it'll be mystery upon mystery until it all comes together in the end, feels tired.
Opus does make an attempt to set itself apart; it's firmly about celebrity worship and the way some can easily excuse a person's objectively bad behaviour because they've made songs or movies we enjoy (we're all guilty of this). The film's music, especially the songs by fictional pop star Moretti (John Malkovich) is pretty good. (He's kind of like Depeche Mode meets the Weeknd) I find it's hard to nail a real world sound for fictional music stars, but they knocked it out of the part with the imitation.
I also really liked the world-building. This cult is committed to an ideology called "Levelism" that feels kooky, yet fully fleshed out (and let's be real, not that dissimilar from the ideas of people like Peter Thiel or Curtis Yarvin).
It's also a really well shot film, with some impressive camera work and stunning visuals; the lighting is great, as are a lot of the costumes, sets, and makeup effects. One scene in particular - with undoubtedly the film's best and frankly, nastiest, kill - made my skin crawl. You'll know it when you see it.
That being said, Opus never quite hits the level of films like Get Out, Midsommar, The Menu, or The Invitation. For one, as lovable as Ayo Debiri is, she's basically playing the same character she always plays; brimming with nervous awkwardness. Her character is boring and essentially an empty vessel, lacking interiority. (And yes, I know this is on purpose. No, it doesn't make the movie better)
I also wasn't blown away by John Malkovich either; he actually felt very miscast to me. He didn't have the gravitas or energy for a role like this to truly work.
The film has bold ideas, but the script feels inefficient. It doesn't drive its points home, its characters feel underwritten, and I feel like the need to make everything "creepy" - as per subgenre conventions - took away from the point of the story. We're not supposed to come into the compound feeling uneasy, it's should feel like a kid getting invited to the Chocolate Factory, but it doesn't.
Opus is feels like someone offering you another appetizer after you've finished a dinner. Even if it's good, you don't REALLY want to eat it. Maybe with a bit of time, you can appreciate it later at home, but it won't be as good as it would've been, had you had it earlier.
