At the age of almost 49, went to the opera for the first time last night. Touring production of Carmen, tickets cost me £22.50 each through a Groupon type website. None of the preconceptions about opera applied. Yes it was sung in French, but there were subtitles. Nobody was dressed to the nines, DH and I were there in jeans and smart-casual tops and didn't feel out of place. It wasn't at all expensive when you compare with other sorts of entertainment (our panto tickets last year were double the price, it's at least £20 to get into a zoo or a theme park). It wasn't boring or difficult to follow what was going on. It was quite long at about 3 hours with breaks but so are some superhero movies.
Not saying it's turned me into a die-hard opera fan but it was a nice evening out seeing some seriously skilled singers and performers.
