Kane going masked would have been so much better then this rey fued he looked so demonic and added to the Fear that the brothers of destruction caused.
You need to quit living in the past though. I agree with you that Kane, with a mask, was amazing and very intimidating, but those days are obviously and very apparently gone. Everyone was under the impression wildly that the bag contained Kane's mask, as well as a possible reunion with Paul Bearer.
W.W.E. did an amazing job by swerving everyone when he pulled out Mysterio's mask. The fact is, Kane isn't any different now then he was before. He's only different because the fans refuse to believe he's the same guy, when sadly.. he is.
The mask is what held the mystique for the fans, and without it they have abandoned and left Kane for dead.. like his storyline Brother did all those years ago. You want to quickly give up on the gimmick, all because it's missing one mask. When the fact is, he's returning very much so to the demonic gimmick he began with.
Listen to his new music, it's similar to his old, with a bit of his new. Look at his new features. Sure he's still some weird guy that can't for the life of him figure out how to get a proper hair cut.. but he's torturing midgets, and if that doesn't strike fear in the heart's of wrestling fans.. I don't know what will.
All Kane needs to do right now, is continue down this path without stopping and giving up, like he has before. (remember when he unmasked? They tried making him demonic, and the character just.. gave up) A feud with Mysterio could be exactly what he needs as well. Why? Because what is one of Kane's best feuds, outside of with the Undertaker.. The one he had with Sean Waltman. (X-Pac)
I think Mysterio against Kane could resemble that, and if it does, even in the slightest.. especially with Kane being destructive.. then it'll be great.
