"Alien vs. Predator: Requiem" is a rare case where the sequel is far superior to the original, but still is hardly a good film. I say this as a fervent fan of both science fiction series that forms the genesis of the AVP franchise and as a person who despised the first AVP entry, "Alien vs. Predator." The first film was simply awful and had very little value in watching the film aside from seeing the big-screen return of the "Predator" creatures. Its plot was laughable and the human characters that populated the film were best served as food dishes to the hordes of aliens. Thankfully, screenwriter Shane Salerno decided to allow these feared xenoforms to the general human populace and provide a concept that the longtime fans of the "Aliens" series has long waited for. If it weren´t for one or two plot missteps and poor human characters, "Alien vs. Predator: Requiem" would have been a clear-cut winner.
The film takes place directly after the events of the first film. The corpse of the scarred Predator warrior from the first film is shown on-board the alien ship. A Chest Burster leaves the corpse and it is quickly revealed that the offspring of the Predator host is the first big-screen appearance by the ´Predalien´ (Tom Woodruff, Jr.); an Alien that takes on half of its characteristics from Predator DNA and is able to produce full-strain Alien offspring without the need of a Face Hugger. For those unfamiliar with the Alien universe, an Alien typically requires a spider-like creature to cling to a host victim´s face and this creature places a single alien offspring into the chest of the host. Eventually, the newborn alien will burst through the chest of its host and enter the world to begin its life of carnage and death. The Predalien simply transfers its offspring, which take on none of the Predator characteristics, by mouth-to-mouth transfer.
