definitely another disaster. Everything based on Alien3 and AR is throwing money to the sea.
The only way to respect these crappy movies and still save the saga is to return where the things went wrong. After the queen being killed there is no way any alien could be in the Sulaco. If you want to make another movie let the hardcore fans envade the last to movies.
Example of how to:
1. as de 2 movie...Sulaco thought lost, engines malfunction due planet explosion. 15 years pased.
2. Sulaco intercepted auto course to Mars base. Solar system is a war zone. Two factions raged in war (in-plot reasons) and eventually Earth became infested by aliens (in-plot reasons too). The population was evacuated and the Moon became and autpost.
3. Another planet with alien presence was located (no matter if the homeworld) the infamous Weyland corporation has its guilts.
4. a) In the alien homeworld alien's hosts must be symbiotic with the spiece. b) aliens are an enginered life form.
5. Ripley, Hicks and Nut leave the chryostsis aging 15 years more. (Nut has around 26, but mentally is a hardenned teenager). Nor Ripley, nor Hicks will be in a hard front line (to old). Of course these characters won't die (they deserve an honorable retirement).
