I should tell you, I should tell you -- if you're not in the movie RENT, you shouldn't be singing along as though you are. This only makes the movie seem as though it's five hundred, twenty five thousand, six hundred minutes long.
I went to see it yesterday and this 12 year old girl a few rows over sang as though she was auditioning and in between songs told her friend 'oh this part is good' or 'this is amazing' and so on. The only saving grace was that she was moved to tears several times and couldn't possibly sing every note of some of the songs. For this reason and her relative young age, I chose not to crush her dreams with my vitriol.
So I'm practically a good samaritan (in your eyes).
