Women's hockey is slower (than an equal level of men's hockey), less physical (than an equal level of men's hockey - particularly since body contact is not allowed), and less skilled (than an equal level of men's hockey)
Now that doesn't mean it has to be any less entertaining, but for many people who want to watch hockey at the highest level, women's hockey is not there yet, and in all honesty, will never be there.
I went to the Gold Medal Game for the Women's National U18 and had a decent time. There was a good level of intensity and my family enjoyed it. But I would be bored to tears having to watch it on a regular basis.
For me it's the same thing in MMA. The entertainment value simply is not there. Not because women are lesser human beings but because they are (and this might be shocking to some people) ... different! *gasp*
