There's very little not annoying about the way the Aliens and Predator franchises have been handled both seperately and together as AVP.
To those that say they want no sequels at all for either, I can't argue against that, because both series are so ripe with possiblities and potential, who could have imagined they could screw up so often and repeatedly with all of them both individually and together. It's obvious Fox doesn't care even slightly.
But Aliens and Predator are two series you SHOULDN'T ever say you don't want a sequel to, because outside of wanting to see the monsters return, they can do ANYTHING to keep their premise fresh. Oh, they don't. But they COULD.
Outside of returning to the original Alien ship on LV 426, which has always been a great unused idea, I say forget the past. An Alien movie can take place anywhere with anyone as the protaganist meeting them for the first time.
Same with the Predator. I LOOOOVE the Predators. They have to do more in a solo sequel than hunt humans. Thats pretty tired now. And they don't always need to be complete douches either. Lets see them in some other setting where they kick-ass. How do the other galactic races see them? Are they feared, hated, loathed?
Here's my Predator solo movie idea. I don't read the novels, so it probably won't mesh:
What if there was an ancient deadly alien race in times past that multiplied
like crazy and destroyed worlds. The Predator, being great hunters, hunted them down over the centuries and destroyed them. The Preds were pretty highly regarded by the galactic races.
But without these creatures to hunt anymore, they had no purpose. Morally drifting, many of these great warriors code of honor deteriorated throughout the generations, hunting anything for the thrill now, sentient or not.
There are different clans, more noble ones that adhere to the old ways, and then there are those that hunt anything.
A human archeological team excavates an ancient alien base and finds thousands of strange creatures in stasis. They bring some to a military space station to study with thousands of personnel. Some of the creatures get out. The station goes silent. Pics leak back to the galactic corp of what the humans have found. They are horrified to see it is the alien creature, long long extinct, now back. Two different clans of Predators leave for the station.
One Clan fights the creatures and saves humans. The other fights the creatures and hunts the humans and soldiers as well.
Eventually the two different Predator clans fight, their differences burning inside them for ages, the fate of the humans at stake. The "Good" Predator Elder kills his opposite. The other clan is now absorbed into his.
Epilogue: Humans review footage of the excavated ruins. from their archetecture and symbols, the race who built it has been seen once before. We see pics of the crashed ship from LV 426. That ship had also been carrying a different type of deadly, long extinct Alien in stasis.
Why? The Predator Elder sees the pic of the "pilot" alien and hisses ferociously.
