I completely agree, Thesbijean...
I can't believe anyone would turn down a free ticket to anything... how can you KNOW you'll hate something just from hearing the title or the idea or a piece of the score? Even if you do still completely hate it (which is unlikely) you'd be able to clarify why your tastes don't coincide with such a piece and how this reflects on your theatregoing...
Even shows you think you wouldn't like could have ONE outstanding performance, a few great melodies, memorable lyrics... or you could see an important show in the career of a performer, director, writer... or you could find yourself in a theater that has housed other shows you've liked... or you could see a performance by some unknown who will in a few years be a star...
I've learned more from "bad" shows than I have from "good" shows, and flops are often just as, if not more interesting than hits...
My grandmother HATED Subways are for Sleeping, and often tells me the story of how her boss made her take his tickets, so she was forced to go... and you know what, she STILL hated it, which is fine, but the point is that at all family gatherings, she makes sure to announce that she saw the best chorus performance of all time... because she kept pointing out who she thought was the most talented person on stage, an 18- year old chorus boy named Michael Bennett. (i adore this story... and my grandma, obviously... she's awesome)
anyway, to each his own, but i definitely can't believe a true theatre- goer would turn down free tickets- EVERYTHING expands one's wealth of knowledge somehow
[title of show] on Broadway. it's time. believe.
