Standard model looks ugly...

I was reading http://en.wikipedia.org/wiki/Subatomic_particle

Elementary particles of the Standard Model include:[2]
Six "flavors" of quarks: up, down, bottom, top, strange, and charm;
Six types of leptons: electron, electron neutrino, muon, muon neutrino, tau, tau neutrino;
Thirteen gauge bosons (force carriers): the graviton of gravity, the photon of electromagnetism, the three W and Z bosons of the weak force, and the eight gluons of the strong force.

and was thinking to myself, holy crap - standard model for sure looks ugly. It looked more like intelligent design theory of physics rather than theory of evolution - that is every particle [species] was created independently instead of being essentially variation on the same thing .

So I looked in the net and even Great Stephen hawking seems to feel that way!

If we understand the universe, then we control it, in a sense. The standard model is clearly unsatisfactory in this respect. First of all, it is ugly and ad hoc. The particles are grouped in an apparently arbitrary way, and the standard model depends on 24 numbers whose values can not be deduced from first principles, but which have to be chosen to fit the observations. What understanding is there in that?

Clearly something needs to be done, and it is not complicating life more by introducing multiple universes [To me all the universes comprise to become one true universe - which is what I would call THE universe. No universes] - It is inaccessible to us is irrelevant. Even in our universe, observable part is not the whole universe - It is only what is called 'observable universe'.
