Do the thriller conventions you have used indicate a sub-genre?
For our thriller opening we did not want to include a specific thriller sub-genre as we wanted to use generic conventions which were found in most thrillers.
Another thing which we did not want include in our thriller opening is any fake blood or anything of that kind as we did not want the audience thinking this was a horror opening instead of a thriller opening.

	We did not want our thriller opening  being too complicated because there is not a whole film to resolve all the enigmas, which doing this will include, in and this would loose their interests they would not understand what would be going on, therefore, we decided to use strict thriller conventions to ensure this would not happen.

We did not want to include any fights to make ‘Music Box’ have an action thriller sub-genre.
We did not want doctors or hospitals involved so it had a medical thriller sub-genre.
And we did not want any weapons to have a crime thriller sub-genre as we did not want to confuse the audience.
