Yes, but that love, kindness, and humanity was put through hell first.
I don't think the studio, Cameron, or anybody they'd get to direct an aliens style film has the guts nowadays to take the audience through that kind of horror before we hit the happy feelings. I think if the franchise deviates from Ridley and Fincher's dark capabilities and style, that it will be castrated in both tone and ferocity. It will be more like halo than alien, and I believe that absolutely.
The problem is that it would likely be successful and spell the end of any future attempts at a serious and terrifying alien film. The xenomorph would be demoted to the ranks of videogame bad guy. Like the locusts or the covenant. And the franchise would never get its teeth back. It would become something tame enough to be featured in star wars.
Cameron knew that and could go dark back in the day, but I believe those days are gone. This is the age of excessive shout outs, unwarranted comedy and spectacle, and restrained and largely bloodless violence. It's the tween age. I don't want to see the beast subjected to circus work. I'd rather it was put out of its misery.
Shining optimism has no place in the alien universe, in my opinion. It has made its bones being the aggressive and unforgiving child of human hubris. A shining example of the nihilistic reality of space, and in many ways, certain facets of our own existence. Let every other space movie (besides "life") have the wins, and love and happy endings. We need one outcast to keep things grounded.
The dark deserves its share of fear and death. And nobody does fear and death like Alien.
