I don't know if "disappointed" is what I feel. I pretty much suspected this was going to be another attempt to pretend all women think, or should think, the same on all issues. Making assumptions about what women think helped elect Mr. Trump in the first place. 
I had hoped the march was going to demonstrate a different model of "winning"  from the one we saw in the recent election: a reaching out to all parties and reflection on what we have in common.
