As someone who watches this shit, let me tell you this show is awesome. It basically is 3 fratdogs acting like pussy's and talking serious shit to ghosts more so than any of the other Ghosthunter like shows.
I love the running theme of every couple of episodes either Zak or Nick get possessed and act more douchey than usual for a couple of minutes, yet oddly enough the fat camera man who's always in a constant state of befuddlement never gets possessed. Bagans meanwhile is constantly in eager young cadet mode.
This and Paranormal State are some of the stupidest trainwreck shows I cant help but watch.
So this is better than Ghost Lab? I like ghost lab cause it's a trio of really fat losers who've somehow gotten Discovery Channel to pay them to wander around a house insulting dead people. Shit, I could do that! I love to insult people who can't strike back. I'd be personal as hell, too.
As for which of these shows is the worst, for me it's really a tie between Paranormal State (Chip Coffee cracks me up though) or EXTREME PARANORMAL. I think the latter only lasted a few episodes though. They literally tried to fight ghosts.
