1. Alien. 10/10 Still the sci-fi horror masterpiece that will never be topped, ever.
2. Aliens. 10/10 Still the sci-fi action masterpiece that will never be topped, ever.
3. Alien 3/Alien: Covenant. Both share Gothic horror sensibilities and are totally bleak, but I rate Covenant a tad higher for its thematic ambitions, back and mouth bursters and Fassbender's erotic dual performance. 8/10 - 8/10
4. Prometheus. 7/10 Visually stunning. Seriously, it's one of the best looking films ever made. Unfortunately the screenplay and editing let it down, however, Fassbender is terrific and it expands the universe. Some great scenes and set pieces.
5. Resurrection. 6/10 Fun and pulpy, weirdly erotic at times and visually stylish. The French influence is heavy throughout. Weaver puts in a solid and interesting performance but it's not a film to be taken seriously.
