I thought that he did extremely well. He complimented LeAnn by saying that he learned what NOT to do in his FIRST marriage. With the limited amount of time he had to promote his movie, why would he waste his appearance talking about petty battles? This writer has no sense of nuance and comes across as petty herself.
As expected from Miley, she gives a contrived, mediocre performance lacking passion, soul and believability. I can't seem to understand what Miley actually does well enough in order to deserve the fame she enjoys. I give her a 'C' as a singer, a 'D' as an actress and another 'C' for attractiveness. There are truly talented people in her age group, such as Jennifer Lawrence, who can actually act and deliver the goods. Good thing her time on the world stage will be severely limited by a lack of talent.
