When watching the opening sequence of the film Taken it is apparent from the beginning that the main character wants to become closer to his daughter, this implies to the audience that something bad is going to happen involving the daughter.

In addition to this, the character drops hints about his past with lines such as "I want to make up for lost time" and "it will be just like old times, but better-know one will get killed" this tells the audience that the main character has been involved in a secret life that involved danger; from this we can infer that he is probably trained in combat and therefor conforms with the Action Thriller factors.
The man is identified straight away as the protagonist and the audience immediately warms to him because of his affection and wanting to be around his daughter. So far in this clip the antagonist is not featured.
