It baffles me when people complain how utterly terrible and lacking in entertainment WWE is, yet still watch religiously. SOL springs to mind, with countless "Cena is shite, if he wins I'm never watching WWE again" only to pipe up first to ask "anyone else watchin Raw?". You really don't have to watch WWE, there are hundreds of promotions out there and one of them somwhere will offer what you're looking for.
Of course there is going to be terrible segments on shows, but to say there's NO entertainment is miles off the mark.
And PG has nothing to do with it, if blood, violence and swearing is what you're looking for then maybe you're better suited to watching a copy of Scarface.
