Just finished it. I listened to it off and on today. My take away, based on years of reading this stuff, is that WWE is a pretty fucked up place, Punk was pretty much reasonable for leaving how he did, though he had lost all perspective with the main eventing Wrestlemania thing, especially when he was so together on so many other things. I actually feel sort of bad for being so excited to be going the Rumble as my first live show in ten years, but I'm a jerk and I'll have shaken that within a month or so.
I'm glad the guy is happier. My two dream jobs as a kid were doing something with wrestling and writing for Marvel so good on him. Hopefully he's got the chops there.
I do kind of wonder if he's gotten the lucha set from Will. Someone should ask him that or if he's so against wrestling he doesn't want to watch awesome 80s lucha. OR maybe not since we know the WWE lawyers will be listening.
