To be honest, it's all subjective. Opinions vary about what genre is best. I have a wide variety of genres that I like. I love a good slice of life show just as much as a good comedy. It's all subjective. My opinion of an epic show will be different from say, Eldin. Does that mean I'm right? Lol probably not.
There have been great shows as recent as this season. Attack on Titan is pretty damn epic. However, the overall quality of show is, not so epic. It's a matter of preference.
