Unless writers overcome these abominable idiosyncrasies or just show me their other kinds of writing abilities that could cover their disadvantages, I would neglect not only their further work, but also their other activities. Basically, I will lack interest on them, unless miracle happens.
for idiot plots or idiotic protagonists
Creating these things only shows either the low intelligence or the pure laziness of writers.
for too much unsolved, foreshadowed mysteries
Incomplete conclusions of books are literally wasting reader’s precious time for these dishonest or sloppy writers.
