Two shows mentioned that I loved were Sex, Love and Secrets and North Shore. With North Shore, it had a strong cast and a good location but much like early Melrose Place, it was too earnest when it started. I thought the show really picked up when Shannen Doherty joined and I was disappointed it didn't continue. I think it could've easily broken out in a second season. Now Sex, Love and Secrets was a huge flop but I remember being shocked at how enjoyable it was. It had a great cast and Denise Richards did a great job leading the show. Unlike North Shore, it went full on Melrose Place from day one. I'm not sure why exactly it didn't work, maybe the bad title?
Two that haven't been mentioned yet, both from Fox:
Pasadena - This show starred Dana Delaney as the head of a rich family with tons of secrets. It was a very strong show that should've lasted longer. The cast also included Mark Valley, Natasha Gregson Wagner and Balthazar Getty. The show was created by Mike White of White Lotus fame and got rave reviews. The lack of success was attributed to the dark tone and premiering so soon after 9/11.
Point Pleasant - This was created by Marti Noxon of Buffy the Vampire Slayer. If I had to compare this to something I'd say The OC meets Peyton Place meets Dark Shadows (or Twin Peaks). Basically, a gothic, teen led soap about a girl who is washed ashore and brought back to life. The mystery was about who she was and I believe there was a supernatural element to it. The show is available on DVD and I think also on YouTube. I'd highly recommend it. It sucks that it didn't last longer but it does work well as a 13 episode mini-series. This show starred Grant Show, Dina Meyer, Richard Burgi, Susan Walters and Aubrey Dollar who I loved on Guiding Light. it hought this would be her big break but it wasn't meant to be.
