Being an avid fan of both Who and Trek, I personally feel that I can't just simply disregard this story. But neither can I ignore its flaws, which is why I seek ways by which to rationalize some of the odd things that happen. Namely, precisely how the two universes cross over. Do they merge to form a new hybrid reality, or is there a "bridge" between the two? And what happens at the end - are they still intertwined or what? The whole idea is too intriguing to just forget about, IMO.
