Aliens

Now this was a hard choice for my third movie to see before you die as i have a lot of movies that you should see and picking one of them is really hard but i went with the fantastic over the top action fest that is aliens.

Now to start off with i know that this is the sequel to alien and that most people hold alien as the best out of the series however I'm one of those people who think that the sequel is better than the original and it shows that all sequels aren't bad as this one in my eyes is better than the original.

The movie has a very simple premise as it See's a group of space marines sent to LV426 where Ripley's old ship the nostrmos originally picked up the alien in the original film and she finds out that there is a colony on LV426 and she believes that they are all dead and she can't be much right.
On landing on LV426 they realize that the base is empty from human life and they aren't alone as the base is now infested with aliens that have acid for blood and an appetite for human flesh, however there is one remaining human in the from of a little girl Rebbecca (newt).

The action kicks off when they discover that there might be human life after they receive the life signatures off the people that were the residents of LV426 however all is not as it seems as there is a dominant threat in the form of the aliens lurking down there.

The movie became a cult classic because of the amount of action and the witty one-liners with Newt sprouting the iconic line "they mostly come out at night mostly" and the other great witty responses coming from the other marines.
As a testament on how great this movie is it still stands the test of time these days as a great action movie and it remains a tuff movie to top as it shows with the other sequels not getting anywhere as close to how great this movie was.

If i had to recommend only one sci-fi action movie to take to a desert island then it has to be this one hands down
