Hilarious read :D
Well, I have to agree with the OP and the posts related to the original topic thereafter.
While non-standard English is a problem -- problem embodying itself as illegibility, that's paradoxally not a major one. In terms of software development; if the code doesn't compile you don't have a problem. Analogous, for a story, if I can't comprehend what I'm reading I have to drop it immediately.
A major problem, however, is when you can understand the text, but small details like PoV and tenses are all over the place. I'd argue that this kind of poor writing pops up just as often on other sites. Wattpad and RRL comes to mind.
After that comes the classic teenaged Gandalf. "Hey, I'm fifteen hundred years old, and all over the story you can read how wise and clever I am. It's a pity I still act and react like the fourteen year old author who wrote this."
The next one is more a matter of preferences. Pacing. (Btw, did you notice the non-standard English I deliberately used there?) Old coots like me don't feel scammed when there isn't a pay-off each and every chapter. In fact, when you're used to reading the old school novels; you know, the funny crap made of paper, then you also get used to the story developing at a more sedate pace. It's still a matter of preferences, so I'd be hard pressed to argue that slow paced is better or worse than pacing suitable for a rat high on adrenalin.
Lastly, and this is a bit off-topic, but this is MY pet peeve -- reviews. If you review a genre you dislike, don't bloody hammer it because of the genre! Show the author the courtesy of writing a review within the scope of the explicitly stated genre. If you dislike harem stories, which I do, just state that you won't comment on that aspect of the story and get on with the rest of the review.
The fifteen cents from someone for whom English is a foreign language.
