My immediate take on "dark matter" was that there is something strange about gravity and inertia.
At the galactic level, however, there is a lot of cases where it seems you can see the mass distribution of dark matter. They've found starless hydrogen clouds that seem to be dragged around by a dark matter halo.
If you think about the evidence from galactic rotation curves you are likely to think that "this galaxy has some dark matter in it" but the modern point of view (which seems to work) is that "this dark matter has a galaxy in it."
When it comes to cosmology at the larger scales I don't really believe in the "multiple flavors of dark matter and dark energy" that is fashionable now. I wonder, for one thing, if the universe is really homogeneous at large scales and if that breaks the assumptions of current models.
