I truly believe we are overly complicating the whole problem.
...dark matter is simply a classical physics solution for a classical gravity problem. It is hoped that once a testable quantum gravity theory emerges, one of its side benefits will be to explain these various gravitational mysteries from first principles rather than through empirical methods alone.
Some Superstring/M-Theory cosmologists propose that multi-dimensional forces from outside the visible universe have gravitational effects on the visible universe meaning that dark matter is not necessary for a unified theory of cosmology. M-Theory envisions that the universe is made up of more than the observable 3 spatial and 1 time dimensions, and that there are up to 11 dimensions altogether. The remaining dimensions are hidden from our full view and only show up at the quantum levels. However, if there are particles or energy that exist only within these alternate dimensions, then they might account for the gravitational effects currently attributed to dark matter.
I have issues with the String and M-Theories also. Again, I feel these are a matter of over complicating things. But in this previous except from the Wikipedia article it suggests that dark matter is a result of a system rather than creating a phenomenon to produce an affect.

A study at the University of Mainz, Germany in 2004 stated "it has been found that if one applies just a standard quantum mechanical approach to Newton's Gravitational constant at various scales within the astrophysical realm (i.e. scales from solar systems up to galaxies), it can be shown that the gravitational constant is not so constant anymore and actually starts to grow. The implication of this is that if the gravitational constant grows at different scales, then dark matter is not needed to explain galactic rotational curves."
As much as this approach appeals to me (K.I.S.S.), this doesn't sound relativistic. Since it was just a straight adjustment of the older Newtonian account of gravitation, it doesn't account for an application of the newer Einstein's general relativity.
Any way you approach it, my belief is dark matter comes down to a fundamental misinterpretation of the nature of the universe we live in. Our perception is limited by our inherently limited physicality. Much like those Flatlanders who were incapable of perceiving the nature of our universe due to their limited physicality.
