Cannibal Ferox is essentially a CH knockoff, it's a fun watch once and a while, but it cannot top the master of all Italian cannibal cinema... Cannibal Holocaust.
The story, the execution, and the gore is much better in CH then CF (Make Them Die Slowly), also i'm more lax about the animal killing in Cannibal Holocaust as it was trying to make a statement as opposed to Ferox which was doing it for pure shock value.
