Well it's not just that.
It's that David Fincher wasen't allowed to do the movie he wanted.
The setting with prisoners is just all wrong - I don't f**king care... kill them xeno, plz!
Killing the hero's from the previous, that also Jim Cameron said about Prometheus/covenant, was
realy something he would never do... (goodbye, john connor...)
When I think of it, Prey and Alien3 is pretty similar...
Forgettable characters - check! all prisoners/all indians... and some minor french fodder you diden't care about either.)
Simple "Jason/Friday the 13th" plot (as someone discribed it.)
"The predator isen't a predator any more/the Alien isent an Alien anymore"-debate it.
