I agree with a lot of what Sergio says to be fair. WWE wrestling, whether we like it or not is in a lull period, it doesn't compare to to the Attitude Era nor even the Golden Era. Slowly but surely, steps are being taken to get WWE back to where they belong, CM Punk for example, whilst I can't stand him I can see he's shook up the company and brought some much needed excitement.
A lot depends on what Triple H does in his new role I suppose, most people are giving Sin Cara the benefit of the doubt here and are sure he'll cut out his mistakes, but it was obvious the fans would not take to him as much when they already had Rey Mysterio.
Why is WWE not as great as it once was? A lack of competition. WWE was so great, it killed off WCW and simply took over ECW. TNA is not on the same level as either of these promotions, but once/IF it is, you can bet your house on it, WWE will be hitting top form.
