BLUF:
Things plebs say to give their boring opinions more supposed weight:
"It didn't have a point."
"The pacing was terrible."/"It was rushed."
"Those characters weren't developed."

The first problem with plebs is their fixation on avoiding that which is "pointless". As if art is propaganda whose worth is determined by how well it beats a message into the audience. Instead of getting enjoyment from the art itself, or engaging with it on any level, they hide behind a misapplied middle school English question. Perhaps I can tell you what the purpose of a technical manual is, or the point of an argumentative essay. I can discern the fundamental meaning behind regulations at the DMV. Looking broadly at life itself, such a point or purpose is impossible to objectively determine, and so it is with art. "What is the point" is itself, a pointless question.
Pacing may be brought up as an objective way to judge quality, and has the added benefit of being a vague term that can perfectly obfuscate the real complaint "I wish they spent less time doing this and more time doing that". Consider for a moment how difference in pace may change the feel of a scene, and how each individual's taste may influence their response. Realize there's no way such a thing can be objectively valued. It's fine. We can still discuss these subjective opinions. For example: Dragon Ball Z has a ridiculous pace when multiple episodes are spent focused on internal monologue and building the atmosphere for a supposedly rushed fight that takes place in five minutes before a planet explodes. As the quality of "pace" can't be objectively measured, a person must explain why they didn't enjoy the allocation of time for the given events. The pleb simply insults the pace and leaves it there, as justification for any opinion. Ignoring the foundation of their opinion, they hide their lack of substance.
Complaints about character development are often a clear indication of shallow plebeian thinking, which requires explicit spoonfeeding to understand anything beyond the most literal. It's as though no character may be "developed" unless we spend a flashback episode watching them grow up! A death can't be sad unless we know every detail about a person's life story! How exactly can a character be poorly developed if they receive the focus of multiple scenes in multiple episodes? Development happens through character behaviour, allowing us to see what kind of person they are. Being told why a person does something is interesting. Being able to understand why a person does something, by perceiving the world from their perspective, is more interesting. Plebs spend so much time demanding answers they forget to engage with the story.
No anime pro should allow himself to be sucked into these traps. An opinion with no argument is superior to bullshit arguments. Don't let your fun be interrupted by the whining of plebs.
