I don't believe Hollywood is out of ideas, someone must have thought that there is probably money to be made from nostalgia. I guess the trend may have started when 90210 was launched at the CW in 2008 and since I had been watching the original on tv tropolis at the time, I thought I should give it a try for awhile, and then I decided to stop watching it after the first season. I didn't trust the CW again until they announced they were picking up a Whose Line revival and that made me happy.
but I don't think they should reboot any more Aaron Spelling produced properties, Dynasty is struggling like crazy, and considering how "well" that Charlies Angels and Melrose Place did.
