Based on your comments above, though, I don't think watching this would change your opinion about anything. People have been more than polite in trying to help you fix your misunderstandings, but you refuse to absorb any new information or change your views when presented with new data.
1. A good understanding of something's basic/fundamental properties doesn't mean that there isn't other more meaningful research to be done and knowledge to be gained.
2. Particle physics in general is considered a mess. There are still many open problems in particle physics and a shiny new accelerator never hurts ;)
Sure there is still a lot more to learn about the inner structure of protons/neutrons but that doesn't mean that we don't have a decent understanding of the overall picture. There still isn't one unified theory that explains all the natural forces, but that doesn't mean that we don't understand gravity/electromagnetism/strong/weak forces in their own right.
I especially like this bit about qcd:
> The mess is so complex that even basic properties of the proton remain unexplained. For example, its three quarks account for less than 5% of its mass, the rest arising somehow from energy of the virtual quarks and gluons.
