Dr. Evil has been trying to find his own GoT clone for the last 5 years. Difference is that his clown show Amazon Studios doesn't hire people with talent and GoT was great until they started running out of source material to work with. So a mixture of competency from the show runners and production team helped GoT succeed. Amazon Studios hasn't hired competent showrunners at any point in the last few years and it shows in the quality of the shows that they produce internally.
