Depending on your tolerance for incredulity and boredom, Annette is a fascinating exercise in how a truly horrible movie got chosen, funded and made. And, you'll find yourselves pondering which careers--particularly Adam Driver's--will be most hobbled by this miserable production.
An incomprehensible script, zero believable characters, poorly photographed, a "musical" score that might work in elevators, and a stunning disbelief about how so much talent could produce such overwhelming garbage, might get you through to the end.
Otherwise, find something else to do for the nearly two hours thirty minutes of this disaster. Whatever you choose, it will be time far better spent than being submerged in the glaring awfulness of Amazon's ill-fated "Annette."
