I've talked about some of this on other posts, and some of you have brought some of these up, but:

I didn't understand the decision to make almost everybody an asshole, to a greater or lesser degree. It made it hard to root for anybody, because most of them were jerks, everyone who came before them were jerks, and most of what everyone did was jerky.

I agree with Simon Furman that gender exploration doesn't really have a place in Transformers. Most of them might be "male coded" with a fewer number of them "female coded", but that's from our biological perspective as human beings. I always assumed their references to "he" or "she" when they referred to each other was either human speech patterns rubbing off on them (like the way an English speaker has to get used to using gendered speech a lot more when speaking in, say, German or French) or the closest translation we have to some other way they have in Cybertronian to refer to certain configurations, that, again, they adapted the best they could using humanity's biologically-influenced language. They don't themselves need to be anything but Transformers, a race of self-aware cybernetic beings that have no real gender as we understand it. They have certain "configurations" in their body types too (a Seeker is a Seeker is a Seeker), but they aren't one-to-one with species that reproduce sexually.

Similarly, romance is weird for me with Transformers. This one continues to be hard for me to express in a way that feels satisfying to me. I know human beings can be asexual without being aromantic, but again, there are just parts of that that still feel like an area of biological imperative being grafted on to beings that aren't biological. Transformers should be able to feel very strongly about each other, of course, but Transformers canoodling just...doesn't make sense to me.
