The company that comes to mind that has always been good about giving talent freedom in devleoping their characters. For example, Matt Hardy has developed his broken gimmick from the ground up and has been given complete control of the gimmick and all that has to do with it. A lot of people in wrestling have touted Matt's creative proess over the years and have always said how he could make it as a booker after he hung up the boots, well this is the first time we are actually seeing that on a large scale. Plus this is a good indication of the positive effect that giving talent freedom can have rather than being over protective.
It is worth mentioning that I don't like the "Broken" gimmick a lot. I don't mind it, but it's just that I feel like it's a little over the top; I do however feel like it is doing good for TNA which is something that I have wanted to happen for a while. As far as this concept goes well the talent is very different then it was back in the 1990's as now they are more skilled in the ring and back in the day it was more about carrying a good promo. But now all or most of the talent seem plain and a lot of the promos are the same, nobody sticks out well except the Broken one. Overall, I think giving the talent more open freedom would help them become more unique and less the same as all the other guys. Wrestling is all about being able to rise above and stick out from the pack and that is why I think Matt has stuck out so well. I don't see WWE suddenly changing their philosphy anytime soon, but maybe 2017 will bring back the slogan of "Anything can Happen in the WWE."
