Try to understand:

Musicals are PURE ESCAPISM .. they are not supposed to be "real life". Like James Bond movies. You have to free your mind to adopt the Willing Suspension of Disbelief, before you can understand or appreciate (or enjoy) a musical.

From there on, it depends on whether the music and lyrics are any good. Many of them are rubbish, of course. But you will also find some really good songs and terrific dancing. == Johnny
