There are a lot of fascinating ideas Green is throwing into Opus, and it's obvious that this is a fully realized concept that he's worked on for years; not only in the script, but in the extra work he's done in fleshing out this world. Still, we don't see enough of that work come across in the finished product, and the ideas here come off as muddled, failing to connect with the audience beyond a superficial level.

Despite solid performances from Edebiri and Malkovich, Opus never takes off. It mostly meanders, relying on leaden expository monologues to move the plot, and rarely delivers on the promised horror of its atmosphere.
