I hardly think there's a thing as a concept or idea that's honestly "bad." It all depends on presentation, polish, refinement, etc. People didn't like your idea because it was basic, done, cliched, without anything much to back it up, along with the ganging up that was going on. Like i said, an idea needs to be done right, different, add some originality and a twist. That's what matters: making a good game, not something that appeals to the masses (although there is some correlation between that)
then again, if you wanna drop it, drop it.
