Yeah, the Alien connection backfired with the folks I know.
When I went to see Prometheus with my brothers, one by one the rest of my family became interested and joined the group. They were intrigued by the premise of the movie, found that compelling, and some of them (my Mom, for example) were on the fence until we told them this was going to be less scary and gory than a typical Alien film. We love scifi, not horror. We like to discuss ideas, not watch girls get attacked by rubber monsters in the shower. I ended up seeing the movie with twelve people! First time the whole family had seen a movie together, and I was 27! And it was the premise, not nostalgia, that compelled every one. It was plenty scary, too, as my Mom and little sister covered their eyes for most of the second half. After the movie, we discussed it for hours. We still talk about Prometheus to this day. It was a rare movie that my SciFi loving family fully embraced. It was my brother's favorite movie for a few years. We loved it. Great experience.
With Covenant, my family has almost zero interest. Hey aren't convinced that it's related to Prometheus in any meaningful way, and looks like a dumb monster movie by comparison. The reviews so far indicate the same. I couldn't even get my girlfriend to watch the whole trailer, much less show interest in going with me. And it's because the weak premise and emphasis on exploitation elements like gore over story. This movie is a huge letdown for every SciFi fan I know. This horror crap is a lot easier than thoughtful SciFi. They chickened out on the setup for Prometheus 2 and made this hollow fanbait instead because its safer and easier. I don't have any respect for safe or easy.
