Which boxing PPV's are you getting? The last several HBO PPV's I've watched have usually shown the main event and a replay of another fight. I'd say the the entertainment value is purely subjective. If MMA isn't you thing or you have no experience with ground fighting and submissions then I can see how the entertainment value wouldn't be there for you. In all honesty I'd rather see a good submission than a KO when I watch MMA. But lets not belittle the sport of MMA by saying it isn't scientific. I don't think you'd say that Sambo, Brazilian Jujitsu, Judo, Freestyle & Greco Roman Wrestling, Kickboxing, and MuyThai are scienceless. These are the disciplines that predominantly make up MMA
