Call it a personal preference but when it comes to live theatre I watch very little other than good ol' Shakespeare.
I have watched other things... Ie. Death of a Salesman is boring! Lysistrata is amazingly funny... But basically a lot of non-Shakespearean plays are annoyingly bad or boring.
Frankly I've enjoyed ballet events more. If given the option of watching Death of a Salesman or watching ballet... I would choose ballet everytime.
Same goes with musical plays like Les Miserables. I prefer the 1998 non-musical version because it has more story and less fluff. I haven't seen the new film of Les Miserables... But I have heard from friends that it sucks. Some people probably won't care however because they just LOVE Les Mis.
But maybe I should point out that I am an hypocrite. I am writing a musical theatre script... Whether it will be very good and get performed someday is questionable.
