I sincerely prefer living dead Nazis of cinema to actual living Nazis in the real world. But enough about me.
Oasis of the Zombies has a lot of actors, big props, and explosions in the battle sequence. Jesús Franco must have had a decent budget on this.
Franco never seems too invested in FX or make-up design so it’s not surprising his zombie movies tend to phone that shit in.
Though slow and not a little dull, Oasis of the Zombies does get sporadically atmospheric once finally rolling.
And yes, it is probably four or five times better than Jean Rollin’s Zombie Lake (1981).
For a much more interesting and amusing take, please see nathaxnne's tremendous write-up of Oasis of the Zombies.
