well, I thought she looked quite odd too, but the advantage to that is that she is using that quirkiness towards the character - so Kristin's Glinda was more Proper, Prim and a Complete Fireball, JLT's Glinda is awkward, out-of-place & surprising - it's different in a good way!
No one touches Kristin though - she IS Glinda!
I'm unlimited, I am wicked through and through...
