First off, the concept is great. It's reminiscent of pimple popping in that it's gross but informative at the same time. You learn about conditions.
However, there are some very questionable decisions made by the dictors here, like shortening an otherwise healthy long second toe. Also people wake up during surgery, which is horrible, but more so if scripted for the show.
It seems that some of these are unnecessarily operated.
Also the extreme gore is unnecessary. These scenes could have just as well been done in B/W or desaturated.
