Resident Evil

The first in the series and one of the best post-apocalyptic films.
I had never played any of the video games before seeing Resident Evil. I was drawn in purely because of the fact it featured the undead, and it was the best decision I've made.
Resident Evil takes elements from the first two entries to the video games series.It features a global company by the name of the Umbrella Corporation, a company known publicly for its investment in pharmaceutical goods and medical supplies, but is also a major player in genetic engineering.
They run a subterranean facility under Racoon City called the Hive, which hosts a research program into a highly secret "T-virus". In the beginning of the film, a thief steals the virus and contaminates the facility. The facility's artificial intelligence "The Red Queen" seals the Hive to prevent an outbreak, killing everyone inside.
We meet the primary protagonist Alice (Milla Jovovich), who wakes up in a deserted mansion suffering amnesia. She checks out the mansion before she is subdued by a man, after a which a group of commandos bust in and arrest the him. Very confusing to read, but the frantic first few minutes of the film set a cracking pace for the rest of the film to use as a vehicle.
The deaths of four of the commandos is a must-see, while Michelle Rodriguez's toughness and one-liners add much break the tension in all the right ways. The introduction of the undead is remarkably done, and is far enough into the film to allow the development of a story, and for the viewers to gain an understanding of Alice's background.
I won't give any of the rest of the film away, but it is definitely the best of the series, and is one of the two best films made from video games in cinema history (the other being Silent Hill).
