Meet the Press is a must-see for anyone concerned with current events, if for no other reason than that it's a must-show for the participants in those events. It's a show with a clear liberal bias, but compared to most of today's news programs I would call it pretty even-handed.
Russert is a skilled interviewer, able to pose a question and then shut his mouth for however long it takes the guest to respond fully, but he has a tendency to become overexcited about his hypothetical constructs, as in "If you knew then what you know now, would you still do what you did?" It's hard to imagine any sane, self-respecting person trying to answer a question like that, but somehow they all take a stab at it. (In fairness to the guests, Russert is so over-enthusiastic with these that he rarely takes "I really don't know," as an answer to such questions.
In my opinion the greatest strength of the show is the way it confronts guests with their own press and allows them to respond to it. Russert is well-known for describing a video clip of the guest that's about to be played, and then saying briskly "Let's watch!"
