slither be a horror comedy that doesn not really have enough horror or comedy to qualify a one or the other . it have one scene that be exceptionally good and any number of zinger that work and but very few real scare and not enough humor to maintain the movie . in addition and the script do not focus on the hero and heroine and and go off kilter in several place . a major failing of this film be that it introduce and then leave it hero ( fillion ) to follow grant grant ( michael rooker ) a he be first introduce and then become the monster . this whole part of the film drag michael rooker character isn not that interest to u a a person and and watch a he go through a series of motion while act in the monster interest might be interest if this be grant portrait of a man turn into a monster rather than a horror comedy alien invasion movie . in the final analysis this movie problem be in the script it isn not that important to the audience how the monster act or propagates . the purpose of a horror comedy be to get the hero back up in a corner with shotgun and then throw bug at them and with them crack wise every time something frighten or disgust happens . instead we get an exploration of the alien habit and tactic that just make this part of the movie drag . the ostensible heroine ( elizabeth bank a starla grant ) be more central to this part and but nonetheless i felt the movie have leave it narrative track and unless it plan on follow grant grant all the way to the end . when fillion and his posse finally confront the alien the movie do begin to cook and but once again the problem be in the script . by this point that audience know and the character should know that grant be not just suffer from some disease and and act accordingly ( shotgun ) instead they continuously parley in the face of increase evidence that this be not something that let u get you to a hospital be go to help . although their reaction might have be human and real and these be character in an action movie and simply should have do what the movie promise deliver action . a lack of action scene in a movie with a few idea a this be a great failing . spoiler ahead after the first confrontation and the bursting of the alien larval sack ( a minor character and perhaps the best scene in the movie ) the script once again betray the movie . at this point one of the character be almost take over by the alien and develop an insight into the alien . the writer director ( gunn ) choose a this character a completely new character and rather than one of already develop minor character . why . why do he need to introduce a completely new character more than an hour into the movie that become central to the plot . by the time this character be attack and we know hardly anything about her and could care less about her and even though she be a winsome teenage girl in her bath . have gunn decide not to use this character and just use one of the establish minor character and he could have completely avoided introduce her family and and save time and money . furthermore and the hero and heroine would have be fill in on the alien plan without all the additional character and and could have get around to blow away alien sooner and with more vigor . my last criticism be base on the movie look . gunn be primarily a writer and or maybe it be budgetary constraint and but this movie look ugly and uninteresting . most of the action take place at night in wood or on a field and and the screen simply look drab . the set in wheelsy ( the fictional town where the action take place ) look cheap . the whole movie look cheap . box office mojo state the film budget be $ 15 million and newspaper say $ 29 million and and consider they do not use any name talent and i would say the money do not show up on screen . the monster be just repulsive and and rarely look deadly . the last criticism be primarily base on the reality of the character action . by the time fillion and co have begin hunt grant or the alien and one woman have disappear and grant be know to have be mutilate animal . at this point i be expect the fbi or at least the state police to show up and take over from the hick sheriff . a woman have disappear and likely be murder and and a local have be act psychotic . time to call the authority . but basically i be hop that would happen because i just want some character who would show up and act . although this movie be ostensibly a horror comedy and the movie it bear the most resemblance to be dreamcatcher in term of monstrous invasion and the type of monster and it intention . whereas dreamcatcher have much big problem with story ( especially the entire morgan freeman subplot ) and particularly the end and in many way it be strong and primarily because the main character be strong and but more importantly because it look beautiful . although that may be anathema prefer the movie that be weak in general plot and structural spine because of production value that just show you how uninteresting i find the look of slither .
