Ah, no - plot-wise they're miles apart.
In particular, in a later episode (can't recall which one), there's more focus on the daughter, and how she makes a living - which is as a model. She's young, self-absorbed, doesn't behave well for her agent etc.
It just made me think immediately of that idea in Zenith of the superheroes being like celebrities, and leaning heavily on that to make a career for themselves that involves little to no actual super-heroism.
So, there's still value, for me, in trying to bring something like Zenith, or Dredd, to the screen. It's just that they would (ironically, perhaps) seem as if they're being derivative, because of the things that have already been brought to the screen that are probably at least semi-inspired by the works in 2000 AD. See also: Firekind.
It's not too much of a stretch to suggest that Millar might have been inspired by Morrison, given the history.
