Well naturally when you take half of your stars off a show, it's gonna be hard to still put on a show as good as it was before...at first. The brand extension exists simply to really give more wrestlers an opportunity to make a good living for themselves and work for the WWE. The WWE created more jobs so to speak through the brand extension, gave them more room to create new stars. The show's not going to be as good because you're no longer seeing all of the best that the WWE has to offer so to speak...you're only seeing the best of what Raw, Smackdown, or ECW has to offer by themselves. Had it not been for the brand extension and even "brand exclusive pay per views", do you really think that a guy like JBL would have ever had the push that he had? Do you think he ever would have been Champion? After he was fired as Jamal in 3 Minute Warning, Umaga would have never been brought back in and given the opportunity that he's had. Arguably, guys like Randy Orton, John Cena, and Batista wouldn't have gotten the exposure that they've gotten over the past several years. You could argue whether or not Matt Hardy, Jeff Hardy, or Charlie Haas would have been given a second chance....or if guys like King Booker, Rey Mysterio, and even Eddie Guerrero would have had the title reigns that they had. Would Ken Kennedy be as high up the card as he is?
I'm personally all for the brand extension and brand exclusive pay per views....and if I were a wrestler trying to make a living in the business, i'd be all for it also. It creates more opportunities.......it gives more guys that deserve a shot their shot. It gives more guys that deserve to headline a Pay Per View a spot as a headliner. The shows aren't going to be AS GOOD as they could potentially be if it were a cross-promotional show...and there's no doubt in my mind that EVERYBODY in the WWE knows that. The reason why WWE's ratings aren't close to where they were in the "attitude era" is just simply because of the brand extension. The fact that Raw is STILL drawing ratings like 3.7 and 3.8 with half the talent is remarkable. So...I really have to disagree with you when you say that "the brand extension went down the tubes".
