Alien3 got a number of things right, and a number of things wrong. Killing off Hicks and the kid was one of the good decisions.
Killing off Clemens before the final confrontation was a wrong decision. Would have made Ripley's sacrifice even more effective if she'd just lost him to the WY gunmen.
Hicks and Newt, honestly couldn't give a toss, not keen on seeing either of them revived for the sake of Blomkamp's preferred trilogy. It's going to be a major stumbling block to enjoying whatever else he might have in store.
