The camerawork
The one thing I really can't stand about the show is that the camera is practically everywhere but on the contestant's lips. They go to the crowd, Crissy Teigen, L.L. Cool J and whatever other guest is on the stools, pull back so you can't see their lips, etc. Just a guess but it seems that only about 15 to 20% of the song is spent showing their lips. Oh, well, there's still The Tonight Show where they at least try to do it right.
If you love Jesus Christ and are 100% proud of it copy this and make your signature!
