Synopsis

In Twinless, two young men meet in a twin support group and form an unlikely friendship. Roman (Dylan O'Brien) and Dennis (James Sweeney) both search for solace and an identity without their other halves and soon become inseparable outside the group. But when Roman meets Dennis’ ebullient co-worker, Marcie (Aisling Franciosi), all is revealed to be not what it seems, as each man harbors secrets that could unravel everything.

Moviegoers are saying
Dylan O'Brien delivers a surprisingly complex dual performance in 'Twinless' that showcases his range in unexpected ways, though audiences seem divided on the film's tonal shifts. Despite mixed ratings averaging around 4/10, viewers consistently praise O'Brien's acting evolution while noting the film's creepy, emotionally charged atmosphere.

Grief is seldom this entertaining.

A shrewdly constructed, heartrending dramedy.

In the end, we’re left to ponder not only grief but loneliness, and the lengths people will go to fight it. Shakespeare had a line about that, too, referring to “the mystery of your loneliness.” In Sweeney’s disturbing but also oddly satisfying tale, that essential human condition retains its mystery.
