I watched this Z-grade excuse for a "movie" under its title "The Man with the Synthetic Brain", but I can assure that any form of brain activity is the absolute last thing you should expect to find here. Now I am aware that one shouldn't anticipate much when selecting a movie directed by the notoriously incompetent director Al Adamson (his other "highlights" include 'Blood of Dracula's Castle', 'Satan's Sadists' and 'Brain of Blood') but this worthless excuse for a motion picture is literally insufferable. The first 3 minutes are the only ones worth mentioning, actually. During this falsely promising intro, we witness a Frankenstein-type monster savagely strangling no less than five people. What an awesome opener, you'd think  but then Adamson suddenly opted for a completely retarded and incoherent narrative structure, involving long & confusing flashbacks and unrelated sub plots. Don't even ask to summarize the concept, as it quickly got so boring and uninteresting that I lost all attention. Apart from during the intro, there's absolutely no other action or bloodshed, the acting performances are almost painful to observe and not one of the dialogs makes a slight bit of sense. John Carradine looks really fatigue in his umpteenth role as unstable scientist (and cause of all horror) and Adamson's direction totally lacks style and inspiration. Even horror fanatics that have a weakness for 'so-bad-it's-good' cinema shouldn't view this dud, as it's too terrible.
