Steel/John Henry Irons is a keeper.
Everybody says Steel. I don't know why that is. I honestly don't really see it.
Intercompany ideas aren't very interesting. I'd rather have a first rate Iron Man than a duplicate Iron Man at another company. And as much as I admire Steve Englehart's work, let's face it: Moon Knight will never be Batman because BATMAN is busy being Batman.
Manchester Black? Wasted potential. Bring him back and turn him into a major supervillain player.
Amok? Good idea, wasted in one issue. Again, build him up into a major baddie with some serious firepower.
Who?
The rainbow blur effect when Superman hits warp speed? Come on, you gotta love that.
That was a pretty neat looking effect, and shows they put some thought into how Superman's FTL worked. Remember how mindblowing Hyperspace was in Alan Moore's SUPREME?
Doomsday can stay so long as he's a henchman for either Darkseid or Brainiac. Otherwise he stinks as a solo villain and shouldn't be bothered with.
I'm not so sure I share your feelings on this. The point of Doomsday is to have a monster big and bad enough that Superman would lose a fight to him, and seriously,
Superman doesn't lose fights to big monsters. Doomsday has no clear motivation, no real personality. One might argue that it is unfair to say this, and after all, he's a big monster, how much personality can a monster have? That's ignoring how interesting Stan Lee for example, was able to make Dragon Man or the Hulk, or how much character King Kong possessed despite not being able to speak.
