Parenthood 10 p.m., Channel 7
This show has really done a lot to forward understanding of Asperger’s syndrome. Tonight, little Max has a birthday party hosted by an older man with Asperger’s who is played by Michael Emerson. That sounds like perfect casting: Emerson is a skilled actor who’ll probably be able to pull this off gracefully and enigmatically. As Ben on “Lost,’’ he was good, but the script often required him to be overly dramatic and make some illogical personality swings. Pictured (from left): Monica Potter, Peter Krause, and Emerson.
