About "Medium" and the Sound of Music sub-plot...SPOILER!!
I was thinking that the teacher would've/should've known that the dark-haired girl could sing well and even though she might've given a bad audition (I missed that part...did she actually audition??), she would've been the better/more experienced actress for the role. I also thought that Ariel the daughter should've/would've been cast as Liesl. Just my 2¢.
