I enjoyed 'Y The Last Man', although I agree that the ending was a bit lame ...
Lobo, Sandman (along with the 'Death' spin-offs), Hellblazer and Marshall Law are all faves ... I also like(d) Judge Dredd, Rogue Trooper, Halo Jones and Strontium Dog (from 2000AD), along with Charley's War and Johnny Red (from Battle-Action) ... I started reading Preacher when it was first published, but I got fed up with Steve Dillon's artwork (I've never been a HUGE fan of his), and The Invisibles left me cold ....
