TAKE THIS WALTZ ½

(Showtime on Comcast) Writer-director Sarah Polley (“Away From Her”) makes her bid to be taken for an auteur with this visually striking, narratively vague story of love, lust, and infidelity in Toronto.

FINDING NEMO ½

(Encore on Comcast) Not quite top-drawer Pixar, but still leagues ahead of other family fare.

The talking and chemistry here are so good that the brawling feels mandated. (PG-13; runs through July 31)
