People keep saying that it was a curse because it's one of those shows where it had a bad aftermath for what happened to most of the main cast after it ended.

Dana had drug problems and sadly didnt get help

Todd went to jail but luckily turned his life around

Gary had his Different Strokes money stolen from him by his parents then had a abusive wife towards the end of his life

I don't think the show was a curse. Lot's of children actors/actresses were exploited by adults. And it really isn't realistic to expect to make a positive transition from child actor to adult actor.

My opinion is that Todd and Dana chose their paths.

Gary's parents chose his path, unfortunately.
