The show is fairly shallow and picks people who are good for light entertainment. So they have two surgeries and one rejection per show. The rejects tend to be people who've had a lot of work already and seeking to tweak it - some of them don't really seem all that serious and were picked by the producers to all a little more color.
Since the show doesn't want to show actual details of the procedures to avoid grossing out their audience, it become the same routine of safe shots which are repetitive.
The "playful" interplay between the two surgeons is painful to watch - feels very staged and scripted.
Once you've seen a couple of the episodes, they start to become the same old. If they were more daring, they'd take the leap and get into the intricacies of procedures which would be very interesting to see what I assume are artists at work.
