Why be good?
Was Jackson Pollock a good painter? The critics at the time certainly didn't think so.
Twyla Tharp's London debut was panned.
The Prius was largely ignored by car magazines, mostly because it wasn't a very good car.
If we define 'good' as showing reasonable skill in the expected areas of performance, then good is not only useless, it's dangerous. Good authors rarely change minds. Good politicians rarely get elected.
The worst thing you can be given as a marketer is a good product to sell.
