The spread and critical case percentage of ~20% is concerning, but with it still hanging at ~2% deaths, this does seem to only be a real danger to the elderly and medically compromised. Especially considering how overwhelmed China is where the vast majority of this is being reported.
There has not been some drastically different outcome observed outside China, so I am not really concerned with their reporting.
Edit: Just considering closed cases, the rate is 11%, which does give some pause. Especially since this does not seem to be an illness that is overcome quickly.
