Most underrated movie of all time. More underrated than Alien 3

Rating: 9/10 (15 September 2009)

To me the alien saga is the perfect movie saga. With the alien saga, every movie is near perfect. Alien was scary as hell and the best in the series, Aliens the perfect action movie, Alien 3 the greatest tragedy (in a good way) of all time and resurrection, now thats a way to bring back a series!
When I first saw both Alen 3 an Resurrection I liked neither of them. It was only after watching both several years later it dawned on me how great they actually were. The extended editions also help greatly. And while they aren't without their problems, they are truly worthy to be part of the series (I think we can all agree the same can't be said for the abominations that are AvP and AvP2).
People always point out what they perceive to be plot holes in the movie. Why is Ripley cloned 200 years later, why not straight away? Easy, while its never actually explained why, it doesn't matter, you can think for yourself. Maybe they didn't develop the tech until then. Hence the 7 failed experiments. In aliens no one ever questions why the narcissus didn't get found until 57 years later with Ripley in perfect condition. How do they clone her with the alien inside her? In Alien3 Clemens uses medical equipment on Ripley, when she first arrives her clothes are bloody, who's not to say that alien DNA can't be already mixed with her blood?
I will concede that the USM Auriga crashing into Earth is major. Wouldn't it kill millions of people? perhaps even had meteor like consequences? Stupid.
As for the characters, they are all perfectly believable for what they are. The cloned Ripley is a fascinating character, but more should have been done with her. Overall its just a great movie, with plenty of action and interesting scenes.
It's undeniable that Alien and Aliens are true classics. Alien3 and Resurrection are also classics, in their own right.
