It's important for a horror movieto grab its audience in the first few moments, as evidenced by the amazing opening scenes of the genre's finest entries.

Considering how many of the most iconic horror scenes are actually the first ones in the film they stem from, it could be argued that a solid first impression is particularly important for horror films.
