I can see why fans of Lobo may have an issue with the New 52 design but speaking as a person who didn't care at all for the old Lobo the new design has at least made me interested in the character which is something. Plus with the right artist the new design has the potential to look pretty badass.
Pre 52 lobo, hands down. The fact that the lobo we've been seeing is probably gonna get killed by that One Direction reject really makes my blood boil.
For people saying they picked new52 because they didn't like pre-52 -- he wasn't meant to be liked. He was a parody of the quintessential 90's anti-hero. He's supposed to be the butt of the joke. You're supposed to like it when he gets one-upped by Superman or whoever. (It just happened that many people didn't "get that" & ended up really liking him earnestly).
