There are some misconceptions floating about, so I'm here to clear them up.
There are people here who honestly believe that everything is subjective. This two-bit, philosophy 101 mentality is only useful for dragging everything down to the same level so no effort needs to be applied in defending something.
Animation and writing quality are not subjective. You can clearly tell that Akira is better animated than Nanoha; you can clearly tell that Wuthering Heights is better written than The Da Vinci Code. I will lay out everything very simply for everyone to understand:
Animation is not subjective
Writing is not subjective
Your enjoyment of either is subjective.
You are allowed to hate something good. Conversely you are allowed to enjoy something that is bad, but something bad does not become good just because you enjoy it.
Are there any questions? Because I am willing to respond to any concerns you might have.
