LOL. If you compare the sales of HJGLC with Hal's former solo, the conclusion can be easily reached as what turns folks off HJGLC book is they don't...
I think Morrison's characters do have depth to them, at least in some cases more then others, although I still don't think it's one of his strengths...
I don't understand why Hal should be held accountable for that. As mentioned by SiegePerilous02 above, the franchise doesn't revolve just around him...
