The plot holes in Talentless Nana sound like the sort of things that go on in 95% of Hollywood movies and network TV shows. Things just never make sense.
We gave up on The Walking Dead, for example, because characters kept going out of their way to do things no one would ever do in their situation. The plot of each episode centered around someone being actively idiotic.
Certainly doesn't seem to hurt the success of the show, though.
That's a shame. Unlike TV shows, though, print media gives the reader the luxury of time. Time to ponder the events of the story, the worldbuilding, what the characters are doing, and whether the plot holds up, while reading the story. It makes flaws more glaring and transparent.
