To watch “Opus,” the muddled semi-satire starring Ayo Edebiri and John Malkovich that premiered at the Sundance Film Festival, is to witness a movie go from promising to punishing.

In Mark Anthony Green's debut feature, also starring Tony Hale, Juliette Lewis and Murray Bartlett, a young writer scores an invite to the remote compound of a legendary musician.
