Last week I went to see Prometheus which made me borrow the Alien series from a friend and watch them this past week. Here is what I thought of them.
Alien - The worst of the series. I thought it was very boring.
Aliens - The best movie of the series. Bill Paxton made this movie fucking awesome and a classic that I can still to this day can watch over and over again.
Alien 3 - It was ok, stupid but still more action than the first one.
Alien Resurrestion - Had a good story to it, but Winona Ryder fucked the movie up. She is cute, but she is a horrible actor.
Prometheus - It was good, I just thought the end was kinda stupid. Tons better than the first and third movies though.
