I like him well enough, but he doesn’t have a character beyond Bad Ass that doesn’t lose. Which is what I was getting at. His entrance is magic, his mannerisms in the ring are great etc. but they work because he is dominant and winning. If he got shut down clean early once he faced the top guys he would not have a character to fall back on. He’s not a great promo. He is charismatic because of his intensity, but it only works because he is booked to win all the time. In WWE he is 30-5-6 with 2 of those losses coming in his last matches and prior to his comeback he had never lost a straight singles match (Triple threat loss, Elimination Chamber loss, 3-1 handicap loss). So he was booked as essentially unbeatable in a 1 on 1 so his gimmick works and he is cool. If he had come in and worked his way up to fight Triple H then got pinned clean in the middle of the ring 1 on 1 (like how Asuka tapped out to Charlotte) he would have been greatly diminished. In WCW he did not lose for about a year and a half, putting him over huge as a monster. And his first loss was not clean.
Essentially his character is “unbeatable guy” which isn’t really a character because it cannot survive being booked differently. Again see Asuka.
I mean if I ask you to pitch a character and your pitch is “Well I never lose.” ok but who are you? “A guy who always wins.” That is a story about a character not really the character.
I’m not suggesting it is wrong to like him (so did Iback in the day he was cool, the story was great long term booking etc), but he was never a great character or worker, he was a great unstoppable force to chase down the heels in NWO or Evolution, and to be pitted as something to overcome. Which is a great thing to have, it is what Brock is essentially these days he isn’t a great character (I mean he almost never speaks) he is a force of nature with which our characters must contend.
