I don’t really think I have ever regretted watching a tv show (not to mention I never watched things like 90210 or Melrose Place!). If I didn’t like something then I didn’t watch it and when I did like something then, chances are, I would still find it ok in the future. I still love a lot of the “kids shows” I watched growing up and I even recently watched through a few of them to make sure I had seen all the episodes, same with “grown up” shows. I’m just not one to regret things like that. Choices in life sure, tv shows? I’ll just change the channel.
