The media product uses, develops, and challenges conventions of horror films in the following ways:
1) It uses typical horror character conventions - featuring innocent blonde girl, mysterious hooded boys, and costumes that highlight innocence and danger.
2) It develops conventions through its plot of adventurous teens exploring a creepy abandoned house and sound design that builds suspense and startles the audience.
3) It challenges conventions with its typography that flickers like candle light at the end, linking to the film's theme of summoning in an unconventional way.
