I just ran through that scene for the first time in awhile. It took maybe 5 minutes and is definitely not "the same three words" on repeat. It took me longer to get to the scene than doing the scene took. A lot of walking, with nothing in between. That'd be my criticism.
Maybe I'm alone in this, but isn't hypnosis and brainwashing supposed to have some repetition in the message it is trying to imprint? If you want less, then by all means I hope other people speak up and Mulan sees it, that's fine. But I'm on the opposite side here. I don't mind the reading and DON'T want to see scenes significantly reduced in length.
