Is this supposed to be...?

Considering the poster is a parody of those Chick Tracts you get from random Christian evangelists on the streets, I would say it's in reference to Christianity. Also mentioning it stars the actress who plays a Goth forensic expert on the show NCIS. It would be odd if this film was trying to get people to become Christian, based on how it seems so far. Hopefully those evangelist films are few and far between.

SATAN HATES YOU is the latest feature film from writer/director James Felix McKenney and MonsterPants movies. The film has been in the process of being shot bit-by-bit since 2005 while McKenney and company worked on other projects, including the acclaimed AUTOMATONS. The next segment of SATAN HATES YOU will be shot in May of 2007 with the film going into full-time production the following fall.

Inspired by films from the golden age of religious cinema such as A THIEF IN THE NIGHT (1972), IF FOOTMEN TIRE YOU, WHAT WILL HORSES DO? (1971) and STALKED (1969), SATAN HATES YOU is a graphic horror film that tells the stories of two individuals and their struggles with Lucifer himself. The film boasts a large ensemble cast, mixing well-known genre names with MonsterPants regulars.

The film stars Don Wood, Christine Spencer, Angus Scrimm, Reggie Bannister, Michael Berryman, Larry Fessenden and Debbie Rochon in a story about two troubled individuals (Wood and Spencer) who begin to realize they’re in the carpool lane to damnation! Inspired by the “Satanic panic” films of the 50’s–70’s, Satan Hates You has all the markings of the kind of unique film we just don’t get enough of these days.

"This film is significantly larger than anything we've done before,” McKenney said. ”With a huge cast and multiple locations around New York, Los Angeles and even Hell itself, I went into this shoot fearing I bit off more than I could chew. But our incredible cast and amazing crew made getting this ambitions project in the can a breeze … It was almost too easy."

I think its funny that the original question here is essentially is the director of "Canniballistic" (Seriously thats how he spells it) who is also the producer of "I Sell the Dead" and 2 of the stars of the Phantasm series working on a Christian film. When I saw that title I never thought of religion. Look at the titles of exploitation, cult and comedies and tell me that title is not far off...

I don't think this has ANY kind of message.

When there's no more room in hell, The dead will walk the earth...

This is low rate christian propaganda, based on Jack Chicks cheesy tracts.
This film is not worth viewing. I do not recommend this crap.

Cockroaches. Determined to survive. Microwave me, WATCH ME COME ALIVE!

i took it as a message to continue living a clean life. drugs and booze are poison to some people, i'm one of them and this great flick reminds me to continue traveling down the path to righteousness and die smiling. great movie great message.
