I have never seen such a detailed documentary of a movie. This is a perfectly fitting tribute to a SF masterpiece. The fact that it was made four decades after the film itself speaks volumes for what an achievement Aliens was. Someone could argue that it is not objective and fair to give such a high rating to a documentary with a modest budget and a professionally routine production, but that is not the point - the point is in the energy that is recognized by fans of the genre, the point is to pay a well-deserved tribute to the Aliens as a SF movie that has become a cult and will be an eternal classic. With its magical influence it has shaped the entire domain of sci-fi creation up until today, and I believe in the future as well. Also, I give it a high rating because this documentary was created out of enthusiasm and not as a commercial project motivated by profit, this is the product of pure love of film enthusiasts and nerds - and as such has a special value. Aliens was a perfect adventure, and with Aliens Expanded I lived it once again, thank you so much!
