2012 Guide Analysis: "Having already opened in the U.S. last Friday where it topped the box-office, reviews for this 3D fourth entry in the vampires vs. werewolves saga were dire, yet not particularly better or worse than the previous sequels. Much like the "Resident Evil" franchise, the 'Underworld' films have been moving away from the mythology-heavy horror mold to more streamlined and less self-serious action fare.
With most of the players killed off in the second film and the mythology explained in the third, the filmmakers opted for a post-apocalyptic style mini-reboot of sorts with humans discovering and then essentially wiping out both the vampires and lycans. As a result only a few are left living underground.
The big draw here is the return of Kate Beckinsale as Selene who is essentially cryofrozen and wakes up 12 years later to kick the ass of both lycans and exploitative scientists. Whatever you think of the films, Beckinsale is the heart of them and still looks great in the black catsuit. Indeed Screen Gems built their entire marketing and promotional campaign around what is essentially stills of Beckinsale pointing guns off screen.
All the high kicking and blood spraying in the world though can't hide a series now fresh out of ideas. A good example of this creative bankruptcy is how the story revolves around the hunt for Michael. Actor Scott Speedman wisely chose not to return for the role, instead the filmmakers pull the old "Trail of the Pink Panther" and "The Crow" trick with a combination of dark lighting, old footage and stand-ins filling in for the character's ultra-brief appearances on-screen.
Charles Dance and Stephen Rea pop in to fill the requisite British veteran roles that Bill Nighy, Michael Sheen, Derek Jacobi and Tony Curran did in the earlier films, but neither is given either a decent character or screen time to sink their teeth into. Done for a fairly costly $70 million, the movies are no longer as economical as they once were - yet there's no doubt plans underway for a fifth one already."
