What are the other two? Do you mean the original Crisis on Infinite Earths?
But, I agree the plot is nothing to write home about. The art is good and the nonsense humor gave me a chuckle. I want to see Grant's "forgotten humanism" that came out in Doom Patrol--a lot of satire on the "bad things in the real world" and characters struggling to cope (Cliff, Crazy Jane, Dorothy). But, I take it that Multiversity will be satire for the sake of satire. The "gentry", the guys on Bleeding Cool interpret, is a metatextual poke at IP holders and corporate owners, but it's hardly a message to make one reflective and glazy-eyed. It's a lampoon. For fun. I'm having fun--I didn't have fun with his serious, over-wrought Infinite Crisis stuff, but as stated am a huge fan of his Doom Patrol run, so I am amused.
Yup, it's CoIE and Infinite Crisis all over again. Hell, you can throw in Zero Hour too when I think about it.
The art is good, but then most comics these days are good that way. I'd rather just get more Doom Patrol from him. Loved that stuff back when it was new. I'm not as it's really just a cheap soap boxing wrapped in unoriginality all around. Morrison has backslide into being a bad lazy writer again... but then as some have pointed out, he's always be a plagiarist to one degree or another, so...
But really, very little if any good is coming out of this thing. At best, it's a time killer.
