First half was AMAZING, second half not so much SPOILERS

When David showed up things went to shits both plot wise and quality wise.

1. Our masters looked like ancient romans and they had only 1 small city with a spaceport in the middle of it...ya thats real natural....

2. Alien gets trapped and airlocked into space...done a billion times.

3. The female protagonist was not a hardcore badass like sigourney or elizabeth. She screamed like a little girl on that swing and she was way too soft. her boyish haircut didnt change that.

4. Rogue AI theme is overdone and Davids ambitions are vague at best.

5. Once again they are about 100yards from eachother but they dont hear any gunshots...

6. people acting stupid like billy crudup following david and getting his face sucked in..
