I tend to be very WWE-centric just because it's what's easily available to me. WWE Network is through cable providers here and one of the major sports channels carries Raw and Smackdown. I try to keep tabs on ROH and NJPW so I have an idea of who some of the more talented stars are, but it's tough to keep track of stuff that isn't televised. You're right about Raw though, I usually just end up watching it in the background. I love NXT though. They're really running something special there right now. Even Smackdown is so much better than Raw at this point, it isn't even funny.
They really need to try to dump the 3rd hour of Raw. Where do you catch Lucha Underground? I've heard good things, but have no idea where you see it.
