There's a black screen and titles apear on it, so it's an example of "titles over black screen followed by a narrative". There's a pumpkin on the left hand side, at first it's a midshot, and the camera slowly zooms in to a ECU.
I think, that the tense and high pitched music, orange font and pumpkin with candles lighted up inside create a sense of a tension, and in some way set the feeling of the movie. I haven't seen the movie, but I guess it's a thriller about something that could happen on Halloween. The use of orange writing and candles in the pumpkin attracted me the most.
