I was totally caught up in it when it originally aired by in the day. Very rarely did I ever make that much of a point to watch a serialized show on TV, and remember I had to tape it on the old VCR when I knew I'd miss it. A very original show back them.
I revisited it lately (all episodes are on CBS' website) and was pretty underwhelmed. It was cool for the nostalgia factor, but if that wasn't there, I doubt I would have got what the big deal about it was. If you want to check it out, it's not a huge time investment as there are less than 30 total episodes I think. It is very Lynchian, so keep that in mind. The first 10 or so are pretty interesting and entertaining for a quirky TV show, but after that, it seems like they were just making it up as they went along and it wandered aimlessly until the cord was (thankfully) pulled.
