My wife and I started watching a few weeks ago. We just got up to the episode where Bryson shows up. I'm amazed at how well this holds up, even after 25 years. Probably the worst thing about it has been the music, and even that seems like an intentional decision. Its amazing how ahead of its time that it was, that 25 years later (really, even 15 years later) it fits the programming landscape better than it did when it was on. I'm impressed it got the two seasons that it did.
I'm not sure how much of the original show was Frost, but I know that history has ascribed the show to Lynch. I am less excited to see where the reboot goes, but after all the flirting between Audrey and Cooper, I'm curious to see how they interact 25 years later.
