LV426 - On Lemmy no one can hear you scream

I was fine with them cutting out the beginning with the colonists and Newt's parents, to be honest.

All of that is explained effectively and visually by the marine's first entering the base and doing their recon, and then later with the revelation that Burke sent them there when Ripley confronts him. The whole first part was redundant because other than Newt they're only purpose is to tell the audience what we already know.
