I had never watched twin peaks when I was younger (in my early 30s now), but my wife recently was talking about it so I watched it. I thought season 1 was great, but season 2 not so much. From what I've read, the network wanted David Lynch to reveal who Bob/the killer was, and he didn't want to do that at all. So on this showtime one he has 100% control, which was a go/no go point for him, which is good because I personally think the show will be better without network meddling. I'm looking forward to it.
On another note, I watched the twin peaks movie 'fire walk with me', and **** that was way more twisted/****** up than the show. I would recomend that anyone that hasn't seen it to definitely check it out.
