High dynamic range & low noise = Good
Dramatically higher camera price = Bad
Even though it uses rolling shutter, the BMPCC 4K readout speed is at only 7.8ms - 16.2ms, thanks to it's fast M43 sensor, which does not create a problem for fast motion. I don't usually shoot kids on skateboards so I don't see it. They'd probably think it was cool and say, Ooh, wicked! if it did it anyway.
"cameras with faster rolling shutters have a more filmic aesthetic than cameras that employ global shutters.
...if you were to compare two equivalent sensors strictly on performance, one with a global shutter and the other with a rolling shutter, you will likely see that the rolling-shutter sensor will have less noise and a wider dynamic range while generating less heat. Now, a global-shutter sensor can be developed to compensate for those aspects, but the costs of developing and manufacturing a sensor with those capabilities will be dramatically higher. In essence, rolling shutter sensors provide good performance metrics while keeping costs down."
