Good concept, poorly executed.
The acting is good, and the firecracker script has some excellent ideas.
The movie turns out to be a little better than the average. Starting from a romantic formula often seen in the cinema, it ends in the most predictable (and somewhat bland) way.
In those long gone nineteen forties children's matinees it was clear that this one was a down sizing of the adventure serials that the kids prized. The fantastic elements which made them memorable had been replaced by guys in suits slugging it out and the occasional model shot crash.The cast played it all straight faced. The studio, that had produced FLASH GORDON, rolled it out without any hint of guilt for abandoning us to the inanities of Sam Katzman at the rival supplier. I still recall the worm turns turn by Byron Foulger however.
