I think the worldbuilding is top notch, and what story they've done has been good, but it's a very, very slow burn.
How is the newest series of Comics from IDW? Good again?
Oh? What have they been doing? If you don't mind my asking on the world building front.
Stuff about the nature of Cybertron and it's place in the wider galactic community, as well as Cybertronian society, both as a place on its own, as well as backdrop for the polticial turmoil that will inevitibly (becuase it's transformers) lead to the civil war.
Cybertron is a hub of intergalatic commerce and culture (finally giving an explanation why cybertronian altmodes have windows) with organics mingling with the robotic inhabitants. Due to prior attempts at expansion going awry, Cybertron has become restrained; energon is rationed and forging of new cybertronians has becoming increasingly rare. This has lead to multiple political factions (not just Autobots and Ascenticons, as they're called in the beginning, but the violent "Rise" movement and the religious Reversionists, who could probably stand to be fleshed out more) taking sides on the issue of whether or not Cybertron should be taken off the leash and allowed to expand again.
My absolute favorite thing they've added, which I hope becomes as much engrained onto the TF mythos as sparks and protoforms have, is the idea of mentorship. WHen a new cybertronian is forged, they are placed into the care of a mentor, with the new cybertronian being like a combination of child and apprentice. The mentor teaches them about cybertronian society, has them intern at various jobs and basically figure themselves out and how they want to contribute to society.
It's the kind of thing that I can't believe hasn't been done before and I love it.
