While I mostly agree with what you said, that last statement implies that he should be frozen in time and never changing which is something I don't agree with.
The problem with a lot of comics is that they're episodic by nature. Trying to make it serialized has essentially devalued the individual issues. We're past the point where we care about Peter dealing with the Villain of the Month. That's why people have been clamoring for the story to progress. It's kinda hard to do that when you don't have a main story to begin with.
