I’m a little more excited than I should be for the return of “Big Brother” (CBs, 8 p.m.), albeit an “all-star” season means a lot of too-familiar retreads in the house when a new group would be more exciting.

The documentary “Anelka: Misunderstood” (Netflix, streaming) profiles the French soccer star Nicolas Anelka.
