Me my friends were originally going to see Star Wars Rogue, but got there late, and saw that Underworld was playing, so we're like meh whatever let's see. I seen them all but barely remembered anything except that it was about some vampire vs werewolf war. My friends went in with no info about any Underworld movies. End result, it was a fun super action packed movie that had some fight moments that will make you go "OHHH SHITT", majority of all the characters were hot as hell, and in the hour and half we weren't bored once as it was just fight scene after fight scene with little moments of dialogue to further the story. If you're looking for some in depth Oscar worthy movie, this ain't it. If you just want to grab a snack and watch some great fight scenes involving swords, guns and cgi monsters, you'll have a blast.
Underworld: Blood Wars
The next installment in the blockbuster franchise, UNDERWORLD: BLOOD WARS follows Vampire death dealer, Selene (Kate Beckinsale) as she fends off brutal attacks from both the Lycan clan and the Vampire faction that betrayed her. With her only allies, David (Theo James) and his father Thomas (Charles Dance), she must stop the eternal war between Lycans and Vampires, even if it means she has to make the ultimate sacrifice.
