I liked Metal for its setup, the whole metal from another multiverse thing was neat.
Dark Multiverse wasn't as exciting, it was just a world of fanfic.
And Scott got the concept of Dark Matter wrong, but well, it's comics so who cares.
Death Metal, on the other hand, is not well setup, the whole Manhattan force came out of nowhere,
I guess we got that from Doomsday Clock and Flash Forward but that's it.
Also did Scott forgot about the Nth metal, Element X, and bloody Totality.
I liked the concept, but the story needs refining, like a lot of refining.
