The genre of this film is a crime and action and adventure hybrid. This can be guessed from the suspense, conflict and from the fact that it is Sherlock Holmes.
In the extract there is not as much conflict and combat as in other film openings. But there is enough to get the audience engaged and interested in the film. For example in the very opening of the film Doctor Watson is giving a narrative of what year the film is based and what is happening in the world at the time. Then the action begins by a street and tent filled with people blowing up.
The suspense in this film is shown straight from the beginning. The first part of this is who is blowing up all these places the anarchists, the nationalists or the other unknown party. The second part is a parcel, simply that is it we see the bottom half a man and a parcel in his hand, which he then gives to another passer by. The suspense in this part who is the new recipient and what is in the parcel. All of which gets revealed later in the film.
The hero is mentioned early on in the extract but he is not seen until near the end and even then he doesn't look like himself. The hero of course is Sherlock Holmes. He might not be described as the typical hero, but he is most definitely a hero. He is shown to be the typical hero by being described by his friend as kind of different to other people. There isn't much else to go on in this short extract to show that he is the hero of the film.
