Albert Fish, the horrific true story of elderly cannibal, sadomasochist, and serial killer, who lured children to their deaths in Depression-era New York City.
While Fish is well-known among serial killer fanatics, I do not know if he is well-known to the general public. He should be, or at least he certainly should deserve the honor. For all the films that have been made based loosely on Ed Gein, it surprises me that Fish seems to influenced practically no one in the artistic world (beyond Joe Coleman).
The biggest complaint about this film from other reviewers is that it is slow and boring. I will grant that it is a little bit slow, but you are dealing with a subject that has limited photos and even fewer videos. To compile this, the director had to stretch things a bit. Maybe it would have been better as 60 minutes, but I am still impressed by the images they were able to find (some I had seen before, some I had not).
I also liked that Fredric Wertham plays a role in here. I was not aware he testified for the defense of Fish, as Wertham is better known (at least to me) for his crusade against comic books and television violence. There is some irony there, I suppose, that a man who defends the insane ends up battling comic books for their erosion of morals.
