I think I've mentioned before that I liked Happy! too, so don't feel too alone.
I am interested to see how the upcoming TV adaptation turns out.
Regarding Morrison in general, I feel like he's made an active choice in recent years to break out of his comfort zone and do some projects that are a bit different to his usual stuff. As well as Klaus, he's done 18 Days and Avatarex with Graphic India, and he's got his editorial position at Heavy Metal which seems to be keeping him busy at the moment.
It may not have got much traction with the wider audiences that read (say) his DC work, but I'm glad he's seeking out new things as I think even his most faithful fans would agree that he's been repeating himself a little with some of his recent work (although I have to say I still enjoyed both Nameless and Annihilator a lot).
