Everyone who is interested at least a little in movies already heard about this film. In the United Kingdom, Chronos became one of the highest-grossed Documentary movies. One word, outstanding!. The film encourages reflection and, although it is not an outstanding work, it is certainly worth getting acquainted with it. You must watch Chronos online. It took me multiple rewatches and a lot of hours on the wiki to understand everything. I guarantee that you'll want to watch Chronos again and again.
