Transformers more than meets the eye

I saw the Transformers movie last week and I noticed that a very small variation from the existing product (plot,theme) can open up entirely new markets (adults). Obviously this isn’t new, however the change was so small it intrigued me. The crux being that there is often a single element preventing your product hitting other large markets. I’ve watched transformer cartoons with the kids a lot and the movie keeps to its roots. The variations are higher levels of realism in the fights, that’s it. You see people dieing rather than death being implied. Really there isn’t any other difference (I’m leaving aside the movie versus cartoon element because the movie could easily have been produced for kids). I’d suggest it’s 95% real juice. The difference simply being battle intensity. So this is leading me to thinking more about this for Saasu and MarketJus businesses. What minor changes open up entirely new markets?
