Although I'm not really a fan of his art, I get why other people are.
In a way, McFarlane reminds me of John Byrne; both were wildly successful in their day and were/are too easily distracted with pissing matches with others in the industry.
Haunt may be Todd's attempt to re-energize himself and/or generate quick cash for his company.
In addition to his toy company, the guy still owns the rights to all the old Eclipse characters (except maybe not Miracleman) and I don't believe he's done anything with those properties yet.
McFarlane needs to hook up with a good writer (like he's done in the past) who will provide new blood and/or perspective.
