Professional wrestling is a world built on compelling characters.
You can book a showdown between two of the most physically gifted performers working today, but if the fans around the world don't care about the people involved then nobody is going to tune in and watch.
Yet, not every star is lucky enough to strike gold with a gimmick like 'The Rock' or 'The Doctor Of Thuganomics' early in their careers and some have to go through a variety of different personas in order to land on that dynamite character. Never forget, Becky Lynch once dressed in green and did a little Irish jig if she won a match in NXT. 'The Man' has come a long way.
However, the most important thing is for the individual or company to understand when something isn't working and adapt their presentation accordingly before it's too late.
In 2020, we are spoilt with arguably the most talented global pool of wrestling talent the planet has ever seen, yet that doesn't mean that every single character presented to us on weekly television is a sure-fire hit.
Some are far from it and need to be dumped straight in the bin in the very near future.
