Ugh. No, Punk's turn just isn't working. He's just not a bad guy. He's totally justified in everything he says and does. And yet he's portrayed as the villain.
For example, him kicking Lawler in the head is supposed to be the dastardly deed that makes us boo him. But just stop and think for a second. Lawler did say that Punk has turned his back on the WWE Universe after he attacked the Rock. And I mean, what, really?! If there was ever a man who is the epithome of turning your back to the WWE Universe, that's the Rock, not Punk who busts his ass for the company day in and day out. Punk has every moral right to be pissed off at Lawler who totally deserved the kick for what he said.
And Cena, acting like he's the better man. Hello? Punk has made a career out of beating John Cena. Why should I buy that suddenly he has something to prove against him?
The worst part is that apparently all of this is simply because apparently Cena needs another title run. Punk is portrayed like the whining heel so John-boy's inevitable victory seems even greater. The irony is that for everyone with just a little bit of knowledge about wrestling Punk isn't really a heel.
