I was very, very sniffy indeed about Burlesque as a supposed art form, but I got dragged along to a performance in Soho a few years ago by some friends - very much against my better judgement, but I sort of couldn't get out of it without looking really PO, plus we were having dinner first somewhere I really wanted to go, so...
I tried and tried to hate it but......it was brilliant.
It was a very professional, high quality production in a beautiful old theatre, and I was completely amazed at how good it was. The artistes were very good singers and dancers with great comic timing. They were certainly not the tacky, seedy, silicone enhanced lap dancers I was expecting. They had more in common with ballet dancers than lap dancers.
It was not what I had feared expected at all; it was thoroughly enjoyable, funny, slick, highly artistic. I don't often like to say I am wrong, but in this case I was wrong. 
And the other thing I loved was the audience. I expected a bunch of leery, sad, peculiar men. How wrong was I? The crowd was eclectic in terms of age and type, but there were lots of super cool hipster/dandy types, people dressed up in amazing costumes, a roughly equal mix of men and women, quite a few gay people, fat boring housewives from Essex, that would be me then oh all sorts. I loved it.
