The Adventures of Hercules (aka Hercules II) (1985) 
Oh dear
I know that Golan and Globus are considered mavericks but they must have been crazy to give Luigi Cozzi money to make this film. While part one was crap but enjoyable this sequel seems to miss the enjoyment factor and turns out to be a completely inept movie! However there is something completely endearing about Lou Ferrigno and his performance and whenever he's on screen I can't help but smile.
I'm hoping that Sinbad isn't this bad which I'll watch at some point this week, but since that has the involvement of Enzo G. Castellari it should be better, but I'm not holding my breath!
