They got lucky to keep their 0 fatalities, could have easily been 300 if one of their significant near misses went slightly different. Their crew rest rules are dangerous, Middle Eastern crew resource management is much worse than US and EASA, and airline oversight in the region is much less independent. Sure it hasn't gone wrong yet, but with how low the number of fatalities is overall that's a bad metric.

Edit: Just to quote the official investigation on an Emirates fuckup: "The flight crew reliance on automation and lack of training in flying go-arounds from close to the runway significantly affected the flight crew performance in a critical flight situation which was different to that experienced by them during their simulated training flights."

That reflects exactly how the rest of the industry thinks about the gulf carriers and their crews. Combine that with non optimal CRM and you have a disaster waiting to happen. They already did this twice, not understanding automation and (nearly) flying a jet into the ground.
