Metacritic reviews

Glides from a mildly off-putting opening across several scenes that waver between sitcom superficiality and sudden, unexpected gusts of feeling, ultimately ending on a note of perfectly judged emotional ambivalence.

Frequently funny, Schechter's movie is also shrewd in its handling of the tensions between longtime friends and co-workers as professional opportunities dwindle and off-the-job romantic drama trickles into the cutting room.

This well-acted film captures a generational and occupational sliver of New York life that rings true.

Supporting Characters tends to meander pleasantly from scene to scene, relying on the testy rapport between its two lead actors.

The fictional filmmaker's rejection of "quirkiness" ends up, ironically, being embraced by the movie itself, but even at its most sitcomish, Karpovsky and Lowe's banter has a contentious authenticity that recognizes these industry grunts as vital and three-dimensional-no matter their nominal supporting status.

Dan Schechter's no-budget comedy about the romantic and professional travails of a pair of financially struggling film editors offers a few laughs, all served up on eyeball-gougingly ugly digital video.

There is a lived-in quality to Supporting Characters that comes from either a strong cast or days of rehearsal – unclear as to whether they had the latter, though they definitely have the former.
