Rey Mysterio Says Retirement Isn’t Is Sight; Provides An Update After Concussion

Course his matches are the same. Virtually all matches are the same as all other matches, unless you're a specialist like Rey, and then virtually all his matches are the same as all his other matches. The WWE talent aren't allowed to vary things.
Take away the drama of any given storyline, any match on any WWE show can have all its participants swapped out and interchanged with any other participants and the match itself will be effectively identical. The only difference would be the specific finishers used, but A finisher will come at the same place. The only differences come in the creative aspect of things.
It's why I usually only watch Raw and Smackdown and PPVs via questionable online means and then in a small corner of the screen while I'm doing something else. I can hear the commentary and drama and follow the storyline progression just fine without bothering with the in ring action. I'll just skip back if it sounds like there's a really exciting or innovative bit, a funny bit, or a complete screw up.
That includes TNA, though I'm more likely to stop and watch the action there and blank the storylines instead.
The only show I watch intently for the in ring product these days is NXT.

The WWE really needs to step up the quality of their in ring action, give more variety in the structure of the matches and the moves used, and allow their talent to be more creative and expressive in the ring.
Using Rey as an example; he's knocking on a bit these days and he's remarkably injury prone. If I'd never seen Rey in his earlier (WCW) career I'd think Rey was amazing at the moment, but I have seen him in his earlier career, and the Rey that we see today is nothing compared to the Rey of yesteryear.
He's knocking on a bit, and he doesn't pull out as many truly flashy moves any more. That all gives him the impression that he can't go. I'm sure he could though, if the WWE would allow it.

Until the WWE relaxes the limitations it places on the talent's in ring performance, I'm only going to watch it for free online. The story aspect of it alone isn't worth paying for.
