WinterTimeCrime No idea what to comment but here in WN, I think novel is about freedom. (Copied from gundam series obviously) Have you watch Karen rider series and feel good with it? I hardly think they're doing well, but still, their toys sell like hot cakes. This is business.
Lets say there's a singer on the street, wearing skimpy clothing like Nikki minaj. Even if her rap sux, do you think she be more marketable compared to a ghetto that can play guitar very well?
Tbh, you're looking and pinpointing the wrong thing in your concern right now. Yes, spelling might be an issue, grammar too. Heck, do you think all writers are as bland and blunt to the point the don't give a fuark to software like grammarly, words document, Google doc to repair their mistakes?
When you yourself start writing, you'll notice that even with all the writing kit you have, mistake still bound to happen. You can proof read, repair, hire some people etc to make less mistake, but what else does it do? I believe that in this world we're living right now, mistake is something can be overlook, unless you're a software writer, mathematician, accountant, scientist, or whatsoever that required precise calculation. Else, like historian, all the word you write is accuracy, until some philosopher debate with you.
Honestly, JKS work weren't super attractive to me too. I personally prefer reading something plain, or what people say it's a stupid piece of work. But does that means they not doing a good job? Some people might have no talent at writing at all, but they got rich imagination. What you're buying from the writer is not preciseness of the vampire, the overview of the world, the length and girth of his genitalia.
What you're buying here is his imagination, how the world was built in the author's mind. His writing is just a mean of literature that make it alive. The more alive he did, the more enjoyable it become. This is just my one cent worth of comment. You may choose to not like it if you want. But as I always says...
You can be what you want as per your own right, but don't lead people to follow your way as If it was the only correct way. Life doesnt goes just according to the road that was already built.
(The author I'm supporting has a hole in his head too by always getting off here and there, but still, I find its refreshing reading his stories as it keep getting unexpected. Had you found your reason to read?)
