Ruben Galindo is one of those sneaky Mexican exploitation directors who makes quickie-movies for the the American market. The cast is filled with fresh American faces and premise as well as atmosphere are typically US high school-like. Only... the production is entirely Mexican! This technique saves the makers a few extra bucks and the fans of this type of cinema mostly don't notice the difference anyway. However, what you can't but notice about "Don't Panic" is the amateurism. The screenplay makes no sense at all as it attempts to blend the mysteries of the occult (an Ouija-board) with an ordinary high school slasher plot. A group of brainless friends summon a demon (named Virgil...not exactly a petrifying name, if you ask me) and this demon soon after possesses one of the kids. How did this Virgil ended up inside the body of the kid?? Who knows... Why does he think it's necessary to butcher everyone who joined the Ouija game?? Not explained, neither... There's no tension and no sense of humor to detect anywhere in the script. Well...at least not intended humor, because the stupidity and incompetence definitely will make you chuckle more than once! Also, if you plan to watch this film, you're better not allergic to atrocious acting. No matter how hard these teen-actors try, they have no acting skills at all. The best part about "Don't Panic" is  as usual  the gore! Screaming Mad George went nuts again and literally stuffed this film with repulsive massacre and entire buckets of blood. I'm not an expert but I sincerely doubt that an average human body contains so much blood. Oh well, if it wasn't for these gory moments, "Don't Panic" would be completely worthless. In conclusion: this probably is one of the only films ever that feature the hero (supposedly 17 years old) battling evil whilst wearing a ridiculous and utterly childish pajamas. Respect!
