Frankenstein Island (1981) 
The well and oft trodden Frankenstein tale is given a twist and is then mashed together with healthy dollops of Island of Lost Souls to create what is the skeleton of Jerry Warren’s Frankenstein Island.
The film tells the tale of a party of hot air balloonists (and a dog) who crash land on a remote island that happens to be the home of a direct descendant of Dr. Frankenstein. The island is also inhabited by a selection of mutants, monsters, zombies, and scantily clad Amazonian women (who we later learn are actually aliens).
With a premise such as this you wouldn't expect the film to be as dull and dire as it is… The low budget is partly to blame, however even though the story had potential in the realms of whimsical cheese the execution was so poor in as much as it is let down on every conceivable side by the direction, acting, senseless plot, and special effects. I’m all for artistic expression but it seems as if the writers got high and shoe-horned every conceivable device that the miniscule budget would allow (and a lot that wouldn't) into the script, meaning that the end result is nothing more than a bloated but at the same time dreary mess of boredom and nonsense.
Ron would love it.
