If you want to watch it, watch it.
When it shows up on something for free, I will watch it because I am curious as to how long it is going to be before the nefarious surgeon is either ‘Dr’. Mengele or a student of “Dr”. Mengele (Mengele would be around 100 years old now). I would also be curious as to whether the film makers tried to pull off a surviving 100 year old man who did “experiments” in Auschwitz.
From IMBd
An older German man identifies himself as a retired surgeon specialized in separating Siamese twins. However, his three “patients” are not about to be separated but joined together in a horrific operation
<snip> fall victim to a demented surgeon who plans to recreate a horrific operation with humans that he performed on his three beloved dogs:
… Mengele sewed Rromani twins together, this never succeeding in other than torture. I mean, really, that is rather obvious. Older German man, twins, experiment, blah de blah.
If you watch it, let me know when they pull that card? I am really curious now. I am guessing not until near the end of the movie when somehow it shall be used as a “horrific” moment.
