Tower is a very unique hybrid of documentary and narrative dramatization. The film utilizes actors to recreate the events of this school shooting with some beautifully rendered rotoscope animation. The events of this terrible day are shown from the perspective of a number of people, including pregnant student Claire Wilson, who's one of the first to be shot, news reporter Neal Spelce, and police officer Ramiro Martinez.
Tower can be seen as an example of using the documentary medium to create a very compelling cinematic experience. The rotoscoped animation is quite well done, with the visuals switching from colour to black and white to reflect the mood of the events. There is even an element of suspense to the film, as it is unknown whether the subjects survived this ordeal, until their real-life counterparts appear on screen. Altogether, Tower is a quite unique and very well done dramatization of this school shooting.
