Not as bad as people are saying. Started good; went downhill, then came back up the other side

Rating: 7/10 (20 July 2017)

If you don't want to read my rant (although I hope the director does), then go straight to the second paragraph.
This had such good potential; good effects; a good premise, but then it just tragically nosed-dived. One reason for this was the ridiculous choice made by the captain and the other was the character responses when the action started. One character was like a drama queen who had just snorted about half a pound of Colombian marching powder. Who knows? Perhaps she had!! But my heart just sank after that and so did the movie! I cannot understand directors who think that making the characters act over-emotionally creates more tension and suspense in the viewer's mind. This is a cheap tactic and completely spoils the realism and the feel of the movie. Why do they STILL insist on doing this??? Let the action create the drama not the hyper-active character responses. Anyway I haven't finished watching this yet, but I couldn't wait another hour to vent my spleen over this. I'll update later.
Okay! Time for update: The second hour went much better with great performances all round. Good movie! A worthy Alien sequel, or at least, a tasty addition to the series, anyway. Don't listen to the haters. It's nose went down, briefly, and it came back up; especially in the third act.
