As a late night cable talk viewer, I liked the McEnroe show on CNBC — a little wacky, like the host, and an eclectic array of guests from night to night. When McEnroe was cancelled, the personable Donny Deutsch’s new show, "The Big Idea," made its debut this week. 
It’s very good — in a different league than McEnroe due to the simple fact Deutsch is great on TV, and is a more engaging media personality. He’s likable, funny, street smart and savvy. This show might make it. A very good start.
