There's plenty to love about MMA. It's provided hours of entertainment and enjoyment to you in your lifetime, and for every card happening on the other side of the world in the middle of the night that's only available on some obscure Fox channel, there's a positive to counteract it.
But on the flip side of that entertainment and enjoyment, there is an unfortunate dark reality: MMA is disappointing. It just inherently is.
From the fights you fantasy-book and never get to see to the injuries to fighter pay to whatever else you want to focus on, the sport will let you down if you give it the opportunity.
