Ellen Gray's weekend TV picks
* ALMOST HUMAN. 8 p.m. Sunday, Fox29.
In the future envisioned in J.J. Abrams' latest sci-fi series, which gets a special Sunday night launch before settling in at 8 p.m. Mondays, crime is way up and embattled police departments start partnering human cops with androids. Not exactly cutting edge, but the pairing of Karl Urban (as angry, damaged human cop) and Michael Ealy (as intriguingly flawed android), could make for a fun buddy-cop show.
* THE CHALLENGER DISASTER. 9 p.m. Saturday, simulcast by Discovery and Science channels.
William Hurt stars as the late physicist Richard Feynman, whose appointment to the panel investigating the 1986 explosion of the space shuttle Challenger didn't quite go the way the people who'd brought him in thought it would.
* LETTERS TO JACKIE: REMEMBERING PRESIDENT KENNEDY. 9 p.m. Sunday, TLC.
You don't have to be a major JFK fan to be moved by some of the letters - here read by famous actors - that Jacqueline Kennedy received following her husband's assassination.
* ALPHA HOUSE, Amazon.com
