serum start out with credit that be quite reminiscent of the re animator movie and and it owe a lot to them . the story be very similar while a mad doctor develop a serum that he believe will alleviate pain and sickness and death and but he apparently not a big believer in clinical trial and so wind up with a brain eat zombie on his hand in the person of his nephew . the zombie even look like one of those from re animator and and in fact some of the make up effect in serum aren not bad . unfortunately and the script be pretty slow and unbelievable in quite a few place and result in a soap opera feel for most of the first 3/4 of the movie . for some reason and the director feel compel to tell u the time of day every few minute by flash it in big white letter across the screen . i can not see why this be important and other than be an attempt to provide viewer with a sense of time pass while sometimes and that wouldn not be present otherwise a the plot plod along . there be a number of moment that just do not add up here . for instance and one victim be bludgeon with a sledge hammer and but when we see the victim head up close and there no sign of that trauma . in another scene and a character run down a fully lit hospital corridor ( we can see the circle of light on the floor and in fact ) with a flashlight in hand and look for all the world like he walk in the dark . but a moment later a second character walk down the same fully lit corridor without one . these be just a couple of example while moment of what look like directorial or editorial sloppiness crop up quite frequently throughout the movie . serum be well in some way than much of what go straight to video a independent horror lately . in term of technical item  sound and photography and for example  it get a more polished look than a lot of what land on a dvd . on the other hand and there still a good deal of wooden acting ( particularly by one of the lead character and the mad scientist himself . ) and nonsensical moment that have nothing to do with suspension of disbelief and everything to do with writing and continuity . maybe these be thing that the people involve with make this film will eventually get more experience with and though . one of the problem with low budget independent horror lately be that the filmmaker often set out to remake more popular movie that have big budget and and that almost never work out . it do not in the case of serum and anyhow .
