    As if the show's writing and story didn't stand well enough on their own, The Better Sister also benefits from having an excellent roster of performers turning in great performances.

    Sure, there’s a corpse at the contemporary thriller’s center, and a killer, and a kooky cop. But the fun is in watching Biel and Banks stretch out and strut in complicated roles with ample opportunity to demonstrate their acting chops.

    Judging by “The Better Sister,” a series can start out being stupid and obvious and eventually make fun of the stupid and the obvious, all the while upscaling its own genre. .... “The Better Sister” finds a groove with characters who are so vile you can’t stop watching them.

    The series is put together with a high degree of structural intelligence; it loops back to key moments and developments with a nimbleness that encourages full attention.

    Sharply crafted show, but far too long at eight hours.

    For all its storytelling sins, The Better Sister handily skirts the most damning one of them all: It’s not boring.
