“Unfrosted” may be the Platonic ideal of the Netflix movie: ephemeral, edible, enjoyable, forgettable.

It’s essentially Jerry Seinfeld inviting everyone in his Rolodex to come on over for an extended hang to parody the current craze for trademark biopics — you know, those corporate biographies of beloved/nostalgic brands: “Air,” “BlackBerry,” “Tetris,” “Flamin’ Hot,” et al. “Unfrosted” gives them the Mad magazine treatment — lightly roasted with a lot of nuts.
