Saw it today, really enjoyed it. The documentary has its own identity unique from all the behind-the-scenes material we've seen before. Memory was very much an art-house style exploration into the feelings that Alien evokes, the symbolism, the ties to mythology. Some great new interviews with Veronica Cartwright, Tom Skerritt, Diane O'Bannon and Carmen Giger. It also goes into the early concepts for Alien and how the story was developed.
I really liked how Dan O'Bannon was finally in the spotlight here, and Giger alongside him. There is a pretty strange opening featuring the
"Three Furies" in a set inspired by the Nostromo. They use this Nostromo-style set a few times in the documentary, showing clips from some behind the scenes material we've already seen to emphasize their points.
It's definitely worth a watch, but I do feel it could have used a bit more run time to more thoroughly explore the material, the movie got lost a bit with the "Alien means this!" bits from a number of film-major types they interviewed.
Jodorowsky's Dune documentary (slightly referenced in this) really nailed this concept, and I feel like Memory got most of the way there, but not quite all of the way. Still, I hope it sees a wide-release sometime soon, regardless of a few shortcomings from my own personal expectations, it was a real treat.
I'll be writing a more detailed review this week.
