I catch your drift, but unlike UFC 151, the co-main is here fairly awesome. For a shot at the WW title, no less.
I don't get why people are so offended by the 'don't buy it' retort. It really is that simple. You have the freedom to rant and rave about an event, but you also have the choice to not purchase it. Go to a bar and watch it for free. Stream it for free. Wait until the event is over and then download it for free. It's not as though you're being forced to buy a subpar event. The choice is entirely yours. And when there are literally a dozen no-cost alternatives, there's really no reason to lose sleep or shed tears.
