Just in case viewers of forgotten what happened in previous instalments, or not watched them all, this film opens with a brief precis of what happened before. This explains how our protagonist, the vampire soldier Selene has had her daughter hidden somewhere even she doesn't know and how both vampires and lycans are determined to find her as they believe it will help them end the war between the two species.
Protagonist Selene is wanted by the lycans, who believe she is the key to finding her daughter and the vampires who what revenge for what she did in a previous film. As the war is going so badly for the vampires she is granted a pardon and invited to help train more vampire soldiers, known as Death Dealers, for the upcoming battle against the lycans who are led by Marius, a smarter than typical lycan. Unfortunately she is betrayed and only survives thanks to the actions of David, the son of a senior vampire... before the film is over they will have to fight both lycans and vampires in a number of battles.
Having enjoyed the first three films, but not seeing the fourth, I was glad of the short but effective recap at the start of the film. The story might not be the greatest but it served the purpose of justifying several really impressive fight scenes both between vampires and lycans and between rival vampires. Some of these were one on one or small scale, others were battles with numerous combatants. All of these scenes were pretty exciting and featured good CGI. Selene continues to be a fine protagonist and David provides good support for her; Kate Beckinsale and Theo James are solid in these roles. Vampire Semira and lycan Marius are decent antagonists played by Lara Pulver and Tobias Menzies. Overall a solid enough supernatural action movie; hardly a must see but a fun way to pass an hour and a half if you like the genre.
