His webshooters failing has happend so many times before BND that you can't even call that a valid point [...]
The first five months all featured story arcs in which his web-shooters failed at a vitally important moment in the story, to the point where EVEN MARVEL admitted that they'd gone overboard with it. So yes, you CAN call it a valid point, because MARVEL THEMSELVES already called it a valid point, so you're being even more of an apologist for Marvel than they can be for THEMSELVES.
[...] getting beaten by supervillains doesn't make you pathetic [...]
It does when they're guys whom you routinely mopped the floor with before, AND they beat you in ways that you USED to be smart enough to NOT be beaten by, AND the overwhelming MAJORITY of bad guys that you go up against beat you. I do not read Spider-Man to see him LOSE a majority of the struggles in his life, superheroic or otherwise.
[...] and ruins the lives of those around him? Please give me one single valid example of that.
Every single time he's done something stupid since the start of BND, everyone acts like that's NORMAL for him, as if he's ALWAYS been stupid and worthless and utterly unreliable in every conceivable way. When Peter disappears for TWO MONTHS, disappointing all of his loved ones in the process, none of them are even SURPRISED. They EXPECT Peter to be a total failure.
