Finished Morrison's Animal Man, and now thinking of starting another. Saga? Good shit?
If you want to stay in the Morrison / Ellis "slightly meta" wheelhouse, Morrison's Doom Patrol run is great (but looooong), Invisibles is great (but also long, and even further removed from any concept of superheroics), Transmetropolitan is great (and has become frighteningly topical again in the current political climate), Planetary is freaking amazing (a bit more "superhero"-y while also being very much a meta-commentary on comics), and NextWAVE is the greatest goddamned comic book in the history of comics (Ellis and Immonen going "let's have some FUN"). I'd also maybe recommend Morrison's Seven Soldiers of Victory, which doesn't stick the landing, but is impressive for what it does do (and you'll probably love 4 of the 7 stories, albeit which 4 will vary from person to person, for me it was Shining Knight, Klarion, Frankenstein, and the Guardian)
Saga is great, but it's still ongoing, and definitely goes through some ebbs and flows.
