I think part of it is that nobody making the TF films can see past the fact the Transformers are mechanical lifeforms and understand they can be relateable just as much as humans. Hence why more screentime is needed on the pointless humans so the audience can get a relateable perspective...even though it's never been necessary. The first film made it work because it wasn't mainly just ONE angle from the human side, it was three seperate stories (Lennox's team, then Sam, then the hackers) that converged into one narrative when they all went to Hoover Dam and while it wasn't anything special beyond an eye-popping final battle like any decent action summer blockbuster, it remained a film with enough unique charm and novelty to do well enough. Except Kruger can't fucking write so he's been trying to copy that for the past three films, except also dropping the multiple angles aspect and only focusing on the one group of humans. Gradually we've been seeing the removal of the Decepticons as the main bad guys ever since, given ROTF has Senator Asshole, then DOTM had the Decepticons relying on pre-existing human connections to get anything done, and AoE saw the Decepticons having become a complete joke in this series in the form of the closest thing to them literally being knock-offs...who were also built by humans and were about as threatening as a stiff breeze to a brick wall reinforced with rebar. That's what Kruger's trying to do. He's trying to make the films be just another generic aliens vs. humans series. And because the humans simply must have most of the screen time, it trivializes the transformers themselves as being little more than plot device siege engine setpieces instead of dynamic characters like they should be in a film named after them. If somebody could replace Kruger and understand that the Autobots and Decepticons don't need to be around humans to be relatable, something every other Transformers writer in history has understood, then we would see the films become exponentially better.
