Uh, no I didn't. I think I've made myself clear on that. You misunderstood. No big deal.
My understanding is Catherine Johnson wrote the "story" if you want to call it that, Phyllida Lloyd also directed the stage production. This was her first time directing a motion picture, and it shows. They are not getting misplaced credit, as you keep insisting I am saying. They are riding coat tails. Do you get it?
Benny Andersson and Bjorn Ulvaeus better have gotten music and lyrics credit because they did write the songs thirty years ago. Why does that mean they contributed anything more to the production?
