I am taking generic for crestor (rosuvastatin). is that good?

Impossible: There is no generic medication for Crestor (rosuvastatin) at this time as the medication is still under patent. The generic name for Crestor (rosuvastatin) is Rosuvastatin and you may be on that med, but it is not generic (and won't be for years). Generic statins currently available are pravastatin, simvastatin, atorvastatin, and lovastatin. All statins have the same action, but some may be better for some people.
