I believe the Pat Finn stuff is unfair...he may not have been one of the best hosts in town during the early '90s, but compared to what we deal with today with all the Dylan Lanes of the world, boy howdy, Finn looks a lot better. I grew up on TJW90 before the '70s version and remember it fondly.
I loved Duel. Not afraid to say it. The idea behind the format is great. I like Greeny, maybe he wasn't the best choice for host. The show itself dragged a bit and could have used some help in presentation. But it was good at its core and it's a shame we don't see more shows in that vein...tougher one-on-one quizzes would fare well on GSN, I bet.
Earlier, someone said '80s LMAD > '70s LMAD, and I agree with that. Door #4 all the way.
Loved "The Chair." Didn't really like "Greed" all that much. Every day Regis hosted Millionaire, he became a worse host. Jim Perry was the best host of any game show in the '80s.
