I can't speak for others, but as a practicing witch and a lifetime Pagan I've never been all that fond of them.
With so much being portrayed on TV as "the way it IS", it actually makes my life harder.
Those who don't know us think we are either a fluffy as some of the characters on TV or think we actually do some of the "magic" that is only possible with a good FX department. Others realising the shows are "fake" assume there are no such things as real witches. How ever you look at it we're snookered.
