Yesterday evening, Katherine and I watched Alien: Covenant (2017) in an IMAX theater in Arlington, Texas. We've seen all six of the Alien movies, including the prequel Prometheus (2012). The best of the six, by far, remains Aliens (1986), which is the only one directed by James Cameron. Although I'm not a fan of science fiction or horror, I like this series. The violence doesn't bother me because it's so obviously artificial. (The scenes in which the aliens are killed don't bother me at all.) The movie, which was filmed in New Zealand, was beautiful. The sound effects were incredible. Our seats shook from time to time. Katherine found the movie too loud, but it was fine with me. The plot was interesting, the characters adequately developed, and the dialogue engaging. It's clear that additional movies are envisaged. Indeed, the ending is such that at least one additional movie is required. By the way, there were two or three allusions to Alien (1979), which was also directed by Ridley Scott.
Here is the trailer.
