This guy, as far as interview skills go, was the anti Robert Osborne. Robert knew how to make the citizens of old Hollywood feel at home, knew how to ask questions to get the conversation going, and he knew how to say nothing while the interviewee just started talking. As a result he got some of the most interesting and revealing information and insights from people like Mickey Rooney and Betty Hutton, who felt at home with Robert and knew they were in friendly territory.
Mr. Lowe acts like these interviews are all about himself, doesn't let the interviewee finish their answer before he hits them with another rapid fire question, and just acts disinterested in general if they do manage to open up. There are some segments of these shows on youtube, and if you watch them you'll see what I mean about his interviews being uncomfortable and difficult to watch.
I give three stars just because he did come up with interesting guests. It's a shame he didn't let them talk about themselves more.
