They still make more money than most shows and have more viewers than most every other show so I think they will be back.
What I see they need.
1. Either go back to 3 judges or put a tight rein on the never ending babble that has them run over every freaking show. Get rid of Ellen, she isn't a good judge and she isn't that funny doing improv.
2. Supposedly they are going back to 1/2 hour results shows, hopefully at least one of the fall 1/2 hour sitcoms will survive that long. Sure it is nice to have more performances, but I think a tighter results show would be better.
3. Cast for TALENT rather than DEMOGRAPHICS. Why DWTS ratings came up was there was interesting people to watch and enough of them could actually dance it wasn't painful to keep watching.
However they won't do that, they will continue to cast 2-3 people they want to win and a bunch of second or third tier talent to fill up the slots.
I think they'd be amazed what would happen if they cast 24 really good singers. Sure the bestest ones may go out early, the judges/producers favorites may go out early, but everyone every week would be a good singer.
If they need something in addition to TALENT to cast for then personality, not SOB STORY, but interesting people who aren't like watching paint dry as the tie breaker between the really really good ones.
4. Ban all the songs sung 3 or more times on the show and pony up the money for some other songs. Really, you make enough money get the rights to more material, and more CURRENT material.
Telling people they sound like they are singing 40 year old songs and aren't current when they are in fact singing 40 year old songs....gah!!!
