Don’t know if you noticed, but in the end Garlador went with making him an outright villain.
And also, comics only have 20-30 pages an issue. There's barely enough story per issue to justify $4.99, there's absolutely no way they are going to put a backup in each issue. The book is called The Amazing Spider-Man. That's who people spend their hard earned money on to read about.
Paul doesn't have a character because the current creative team doesn't want him to have a character. The end.
It's not like the writing in this run has been stellar on any account. Paul is only one sympton. There are multiple ways this run alienates the audience, starting with a Peter Parker who has spent much of this run falling down after a few punches and being wholly ineffectual.
And now, I'm going to go back to discussing Mary Jane, because she's the topic of the thread. Not bad writing and plot obstacles that are going to be memory holed as soon as this run is over.
I agree no one is angry. We're just bored and tired of having our time wasted with the obvious spinning tires going nowhere.
And I think you're confusing Jonathan Caesar with another character? Caesar is the man who was obsessed with MJ and kidnapped her around ASM 308-309 - a story that once again demonstrated MJ didn't need no stinking super powers to take care of herself - and to save Peter as well.
