I don't see why this show can't stay on ABC. I still feel that ratings aren't correctly charted these days.
If it leaves ABC I hope they will shop it around to other networks or possibly cable. I can see this program having 9-13 episode seasons on USA, FX, AMC, Sci-Fi or Bravo in the basic cable market. Showtime and HBO could also be good fits for the show in a last resort pay cable market. That would alienate some viewers, but at least the programs would eventually hit the home video and rental markets.
I just don't like this axing of popular shows simply because they are not wildly popular. Not every has the lobotomized low-road Shonda Rhimes touch when it comes to ABC programming. Pushing Daisies is something the network should be proud of for balancing their smarmier Bachelor and Grey's Anatomy-style programming. This is like Disney telling Americans that apple pie won't work on network television. Forgive that more traditional moment from this less than traditional Frogboy.
