Actually I mostly like the franchise the way it is, the thing I love about Alien's that it might be so easy to emulate (superficially anyway) the 1986 film over and over, but it rarely ever does so, instead of rehashing the arguably most popular entry into the dirt, repeatedly following a family lineage and retconning itself over and over again (see Halloween, The Terminator, Star Wars) it's always a different take on the material.
I LOVE Alien The Cold Forge written by Alex White, I LOVE Into Charybdis even more, Phalanx's superb, and a lot more novels to come already announced for next year. And between David's Drawings and them that makes the prequels more than worth it.
And because of the rather mature (even for Alien yes) subject matter explored in each one, with a more controlled traditionally lucrative intellectual property, they might never have got the green light. Actually we can see this in effect now with Marvel's Alien full of tracing and awful storytelling, then compare that to the myriad of creator driven projects with Alien under Dark Horse Press, Kilian Plunkett (Labyrinth), Mike Mignola (Salvation), James Stokoe (Dead Orbit), the list goes on for days.
Alien The RPG's the most profitable and successful in that genre outside of Wizards of the Coast publishing. Alien Isolation's just perfect. The Anthology's only beat by LOTR in terms of the Special Features. The original looks stunning in 4K.
Oh and Noah Hawley, the mind behind Legion, gets free reign on an Alien TV Series and he thinks Aliens and Alien³ both rule?! Yeah I'm really happy with the way things turned out. For the most part.
