You're all being a bit harsh on The Biz.
He has used the looser, marker-heavy art style for at least the last 10-15 years (as far back as his occasional issue of Hellblazer if I recall).
This was never going to match his best work, even of he hadn't lost interest early on in the project (which in fairness is something I have noticed before with some of his other non-2000AD work).
Still a 2000AD hall-of-famer for me.
And I liked his cover this week too.
