This documentary film is about the one of the world's biggest electronic dance music festival, Tomorrowland. It takes place in three different countries, and hundreds of thousands of people discover happiness and more in a magical wonderland."This Was Tomorrow: Tomorrowland Presents..." is full of people immersing themselves in pumping dance music, thoroughly enjoying themselves. It is very nice to see hundreds of thousands of people all dressed up, taking having fun very seriously. It is nice to see a woman who met her husband in the first Tomorrowland, and she has gone to every one of Tomorrowland since. It is also very nice to see that the party has an inclusive atmosphere, such as the older gentleman and the two deaf girls. There are times when the film tries too hard to hard, such as some participants talking about how Tomorrowland is the life transforming experience that completely changed their life forever. Though it is true for that individual, I just think that this sentiment may not echo with all the viewers.This documentary is more like a long commercial for the party, but it is an effective commercial and gets me interested in it.
