Definitely agree with the culture element. I'm from the North West of England where you'd find a Jim Breaks or Brian Maxine type in every pub. Watching WoS with Brits, the harder bit to grasp is the differences in logic between it and most US or Japanese wrestling. For example the way wrestlers flip and roll to "go with the hold", or generally taking a bump off the turnbuckle rather than sticking to the corner. I think this is the biggest reason it struggles to garner a stronger following.
