The purpose of the trailers is to enable me to judge whether or not to spend a ticket on a full show. If the trailer is bad, the quality of the full show is irrelevant, because I'm not buying the full show.
As I said before, Melisa is very pretty, but if her dancing is capable of pleasing me, I have yet to see it happen. And it's not like I'm short on dancers who can impress me. Morgaine, Susan, Ellen, Julya, Vicky S, Mina, Tarra, Chems...the list goes on and on, and Melisa isn't on it, at least not so far. It's possible that eventually I'll be able to fit her in based just on her looks, but she has tough competition.
