What Other Models Are There Besides The Standard Model?

The standard model really bugs me, and strikes me as bad science.
In science, aren’t you supposed to discard a model that doesn’t work?
Instead, with the standard model, every time it fails we tweak it to make it fit the data.
Isn’t that backwards? Isn’t the model supposed to predict the data?
The current version of the standard model is
the original “standard” model +dark matter+ dark energy+ dark flow +…
When does it end?
It strikes me like hypothesizing that everything that is blue in the word is the Atlantic Ocean…and the other oceans…and the sky…and blueberries…and bluebirds…and blue crayons… Eventually you have to say the original model was just wrong.
I was reading about this one guy’s “effect based model” which seems to fit with string, superstring and M theory, but challenges some of the preconceived notions about quantum theory (such as the existence of the Higgs boson and the categorization of the particle zoo.)
Unfortunately, the guy seems to be unpublished. I don’t know if this is because he hasn’t been able to get his work accepted anywhere due to bucking the accepted model or if he hasn’t even tried to get published because he knows he is unlikely to publish anything that stinks of scientific heresy.
So what other Models are there besides the Standard?
Is anyone else out there preaching scientific heresey?
