Thought I'd start a new thread for these four issues and leave the last thread for people who read the second trade to comment.
The first issue of the new series starts with an Ironhide/Optimus Prime chat. It kind of feels like an extended Mosaic and is very much a discussion with a few flashbacks thrown in. Both aspects are interesting. The art though... Adopting the movie feel is not too bad. The added complexity to the robot modes isn't too far removed from what we saw in the earlier IDW series. It's just the faces. Well for me it's the teeth (and Prime's retractable faceplate) that just look wrong.
The second story has more traditional looking character models, but the style and colouring make me think of the earliest Transformers tie-in books. I prefered it when I saw the previews in black and white, but it grew on me. The story features the giant Astrotrain as seen in TFTM but somehow makes him seem even bigger than in the film.
There's a throwaway line describing the tapes as Soundwave's children. I don't think it's meant to be taken literally as it clashes with Megatron: Origin (even though I tend to view that as an Dreamwave comic published by IDW). If it is I think it's the first time in canon that Soundwave has been called a parent to the tapes, and that's an idea I've personally never been a fan of.
I generally like how these two stories seem like two short Spotlight comics and look forward to the next three issues.
