ABC debuts Once Upon a Time tonight (Sunday 10/23) and this Friday NBC rolls out a similar series, GRIMM. You can even catch the first 20 minutes of Grimm on NBC's website. This sorta reminds me of the launch of Pan Am and Playboy Club, two retro series that were likely inspired by the success of AMC's Mad Men. And unfortunately, I think the result will be similar with ABC having much better success than NBC. So, what's your guess as to the likelihood of success for these two fairytale inspired shows?
