The Sin Cara feud has to have been one of the most confusing feuds in recent memory. The WWE made it so two men who wore masks had the same ring attire.
It was only recently that the WWE allowed the "evil" Sin Cara to switch to a different mask and ring attire from the baby-faced Sin Cara. It didn't make any sense from a story perspective—as both wrestlers were trying to keep the name and fight over the identity—but it helped audiences from getting confused.
It also didn't help that Sin Cara had mostly been a silent character since his debut, and because of this no one really knew what was going on. Sure, the "evil" Sin Cara explained why he was trying to steal the "good" Sin Cara's identity—but there was no buildup. He just came out and said it.
Outside of the ring, it was well known that Sin Cara had been played by two wrestlers, Hunico and Mistico, but the average wrestling fan isn't going to know that. Hunico took over the character when Mistico was suspended for having violated the WWE wellness policy, and the WWE kept the character going because they didn't want him to lose momentum.
It turned out to be a mistake.
The WWE could have used the Mistico-Hunico story as a way to make this interesting—by having the feud slowly build momentum and have only one of the men have the right to the Sin Cara mask and entrance.
Instead, the story just seemed like it was thrown out and left half-finished for all of the fans to figure out.
The match showed. The entrances received little reaction from the crowd. The match itself wasn't terrible, but the fact that the "good" Sin Cara won says how much faith the WWE has in the feud.
For a win like Cara had against the "evil" Cara, it hopefully means that the WWE means to wrap this feud up quickly. What they will do to the loser or the lesser performer remains to be seen.
Tonight showed that Cara versus Cara needs to end quickly, as it just isn't catching on.
Having two characters who look the same as these two have in the past, or have the same name as they still do, is just terrible. It causes confusion and makes it impossible to build a character into a commodity or a brand like the WWE needs it to.
The feud is a dud, and this match hopefully not only showed it, but ended it as well.
It seems that the WWE has learned the hard way—putting two faces on a man without a face just isn't interesting.
