I actually bought it myself a few weeks ago. It really is amazing. The interview taught me a lot about him I didn't even know. Not to mention, the matches on the bonus disks are AMAZING! Worth the $37, imo.
Also, to the person talking about the AJ/Cena messages being for Ambrose... I considered that too. Until AJ said "you hacked into John Cena's phone?" "Cena"... not just Jon. :/
