While this entry of the "Fantomas" film serial isn't as intriguing as the previous two installments (which would be "Juve Against Fantomas", which I rated a 10, and "The Dead Man Who Killed", which I rated a 9), "Fantomas Against Fantomas" certainly has its moments.
Full of suspense and mystery, this entry definitely isn't bland. There's some really memorable stuff here, like the party that Lady Beltham has in which a man is found dead outside of, or the ending which I will not spoil.
The film is also follows the footsteps of "The Dead Man Who Killed" by being slightly bleaker than the first and second installments. While it doesn't get as dark as "The Dead Man Who Killed", the overall plot itself has plenty of things simply going all wrong!
