Loved it.
Full-on craziness which, if approached in the right frame of mind, is pure entertainment. Great music really well sung, a fully committed chorus who worked their socks off to sell the show to you throughout and a plot line that just about holds it all together. The central performances are quite amazing and I found the whole thing thoroughly entertaining.
If you like Bat out of Hell music, or are just a bit of a rocker at heart, the go for it ...!
