There have been eight Alien films at this point and only the first two were good -just stop making them already.It a comment I can relate to except I don't think it needs to be the end of the franchise. I'm not talking about reboots here, rather I think any future Alien-themed properties should be in the form of video games.
Putting it nicely, Prometheus and Alien: Covenant are not good films. The visuals are well shot courtesy of long-time directory Ridley Scott, but other than that the mystery is poorly revealed, the horror bits are cliche, and the plot is a total mess. For whatever reason the writers chose to ignore most of what the previous movies had established, resulting in contradictions all over the place in terms of the Alien lifecycle and overarching timeline. I could go on a rant about all the inconsistencies, but I'd prefer to keep things positive here (and more importantly - constructive).
The Alien franchise has followed a very bizarre course over the years. It's started off as a very simple, but well thought out (and executed) melding of sci-fi and horror. As more and more films have been released for the IP though the premise has become increasingly muddled until it degenerated into the brain-dead wrestling match that is the AvP movies. Then it flip-flopped hard and turned into a bunch of pretentious nonsense. A video game adaptation could potentially give this franchise some much needed grounding, structure and balance. Of course, it would still need a competent storyteller which might be too much to ask of the video game industry. Hmmm...I wonder if John Gonzalez is available?
