If you're going to make a film that sticks to the playbook, or playbooks, this is how to do it: CODA is a radiant, deeply satisfying heartwarmer that more than embraces formula; it locates the pleasure and pureness in it, reminding us of the comforting, even cathartic, gratifications of a feel-good story well told.

Siân Heder, who came up as a writer and story editor on “Orange Is the New Black,” has directed just one previous feature (“Tallulah”), but she’s got the gift — the holy essence of how to shape and craft a drama that spins and burbles and flows.

It’s a crowd-pleaser, to be sure, and a little on the corny side, but it’s so unwavering in its sincerity that it manages to hit all the right notes.

It’s a crowd-pleaser that works its formula well, even as it breaks new ground.

It becomes pretty obvious early on that CODA is one of those movies where you know where the story is going pretty much the entire time, but the elements harmonize so beautifully it still sucks you in.
