there wasn not much thought put into the story line on many front . this be a good action movie but that about it . the movie state that the lycans be keep to protect the vampire during the day . yet they be keep in cage and have collar on their neck . so they can not turn into their wolf form or do anything any other slave can not do . how do this protect the vampire during the day . who be they protect the vampire from . the uncontrollable lycans . the slave in human form be nothing more than peasant . my understanding be that vampire be immortal and do not age . yet sonya age from child to adult . do they just stop age at a certain age . i understand that viktor be old because he be turn ( a explain in the second movie ) . but vampire baby age . strange . i do not realize that vampire need torch to see at night . yet we see them carry torch throughout the movie . silver be the only thing that be supposedly able to harm lycan . yet wooden steak fire from the huge crossbow kill the lycan too . these be just some of the thing that show just a lack of thought put into the story telling .
