To be honest I've not seen the show, but are they promoting it as mma?
If they're just putting martial art against martial art you can't compare it to mma. It's like putting a wrestler in against a boxer & complaining that the boxer has no takedown defence.
However if it is things like judo verses karate, why?!?!?!?!?
Everyone saw what stand alone martial art is dominant. If there's betting odds put your money on the bjj guy!!!
