Keola Racela's Porno is a return entry to the comedic horror genre follow other predecessors like 80s director, Fred Drekker (Monster Squad, etc.). This film is set in the early 90s and makes reference to 60s satanic films.
Using that mix of satanic popular films and early 90s pop cultural references (Encino Man, etc.), one can see that horror cinema people have the theme of humor from the past 80s films like Fright Night, Return of the Living Dead, etc.. Interestingly enough, Racela pulls it off considering his prior filmwork slanted toward a possible an art-house audience.
The plot is nothing new, that using a movie theater as a site of terror. Lamerto Bava's Demons, that place characters in a locked demonic cinema, but even then reviewers have forgotten other films involving horror and cinema theater. Film's like Bigas Luna's Anguish, Willard Huyck's Messiah of Evil and even Craven's Scream 2 have good fine-horror in cinema scenes.
But what's works for this entry is that interconnection to popular culture, of course with the psychedelic effects toward the progress of Porno's premise: a Demonic theater. Those effects similar to Franco's Succubus (Necrominon) some creative liberties of Succubus creature.
