I am under no circumstances saying you can't criticize art or say that the writing was bad or whatever you seem to think my position is.

Writers can and do get fired for not doing the job they were hired for and rarely get to lead the creative process (and usually if they do they're like, writer/director, or a big name). All I'm trying to say is that a worker can do a good job within the bounds they're given and still have the result be terrible because the bounds were terrible.
