Underworld Evolution is basically one long chase-fight-chase-fight scene, so is definitely not as good as Underworld. There is no real politics, just a 'supernatural cleanup crew' whose job is to keep the whole vampire/werewolf battle out of the media as much as possible, and their own existence a secret.
They use human agents, but it turns out their leader is the first immortal. Selene and Michael, with his help, must try and stop his sons, Marcus and William, who is part of the the chase thing. Marcus wants to free his brother William, the first werewolf from hundreds of years of captivity.
At the end, it is a hybrid battlefest, with a helicopter.
