<human>:  I am looking for good documentaries to watch, which ones recommend?
<bot>: There are numerous great documentary films to choose from, many of which have won awards and critical acclaim. A few of my favorites include: "Hoop Dreams" (1994), "Man on Wire" (2008), "The Act of Killing" (2012), "Citizenfour" (2014), "20 Feet From Stardom" (2013), and "Icarus" (2017). I also recommend checking out the "Greatest Documentaries" lists on IMDb or Rotten Tomatoes for additional suggestions.
