This was a solid story that moved with pace and had fun with its plot and characters,
I enjoyed this one! It felt like miniseries made more progress than its predecessor and there were some good character moments.
I was optimistic from the very start, as there seemed to be small details (for example, the visual parallel with OP and Megatron both striking their hand to indicate a shift to a more aggressive strategy) that were so quick, but so effective. Moments with Sixshot, Ratchet, and the reawakening of Starscream also really worked for me - there was just a lot of personality all around.
Admittedly, I have mixed feelings about the Headmasters, but the series has a fairly irreverent attitude to them itself without making them a complete joke, which I appreciated. The body horror that arrives with the revelation of what has happened to Sunstreaker, however, is actually pretty sinister - again, effective.
I also liked the art. I often struggle with pinpointing what I like or dislike when it comes to art, but I can certainly say it was good here and I liked the variety of facial features and expressions in particular.
My only issues are minor and nit-picky: firstly, getting confused about Ironhide being in Warsaw (I probably just missed something making clear he wasn't suddenly in Poland...), being a little surprised that Sentinel received so much attention in earlier series when Nova was going to be more central, and a few bits of clunky dialogue.
