I'm surprised the word "grindhouse" isn't used on the packaging of this Al Adamson double feature. Despite the box office failure of the film Grindhouse, more people are familiar with the term now than ever, so it looks like Retro-Shock-O-Rama missed a chance to cash in on the free publicity. Both of the features on this two disk set were produced by Independent International, a company founded by Adamson and Sam Sherman that supplied exploitation flicks for the grindhouse and drive-in circuits of the 60s and 70s. No one would ever accuse Independent International of turning out classics, but some of their flicks including 1971's Dracula Vs. Frankenstein and 1969's Satan's Sadists have become schlock classics -- not great films, but fun little bits of exploitation fluff.
Retro-Shock-O-Rama had a pretty good idea here, presenting this double feature in its natural habitat so to speak, buffering the features with vintage drive-in concession ads and trailers, but they lose serious points by not making it possible to play all the features in sequence. You can access either film or the intermission segment from the main menu, but there's no "play all" function. Unfortunately, that's the least of this double feature's problems. There are some things to recommend about this release, but sadly neither of the features is one of them.
