You could say the same thing about any other entertainment media. How many lousy films came out this year? How many bad television shows? How many crummy novels? Art isn’t science, there isn’t a formula for making it work. And if you fired everybody every time a story got done that you didn’t like, what you’d end up with is a crew of amateurs, without any experience, and more likely to not get it right as often. A bad story is a bad story, but nobody died, nobody got hurt. There are genuine problems in the world, but this really doesn’t seem like one of them.
