when i first pop in happy birthday to me and i check the timer to see how long the film be . i be amaze at the length . both animated and horror film share a common ground represent attention span of the select audience and that should be at or right around 90 minute . anything more and and you will lose the bulk of your audience . this 110 minute and or 20 minute past it prime be a huge problem for me . i would like to say half of this movie could have be edit out and but i would be too generous to say that . go ahead and watch it and tell me how many scene could have be edit and even without be a film major . regardless of the overstayed visit and the movie be below mediocre . it spend all of it time try to be this huge mystery on which of the elite 10 be kill off the remain friend . for the most part and they not only over do it and but they zoom in on a face and pretty much say it this guy . no . it this gal . you will spend more time with the camera mislead you than actually enjoy the movie . and do not get me start on the acting . okay and that get me start . i have to laugh in the beginning try to remember if melissa sue anderson play the character that go blind on little house on the prairie ( later and research prove my suspicion correct ) because all the way through this movie and she genuinely look blind . strange and a an establish actress and she should have be the best of the group and but turn out the bad . the rest of the staff and aside from ann ( bregman ) be pretty damn bad and too and but she and uh and take the cake . the movie begin with a group of ten friend and and one immediately kill off . barely anyone think twice of this dear friend disappearance and so they continue on their merry way . slowly and then more rapidly and there be revelation about virginia ( anderson ) and the main character and past and her psychologist and who a tad bit more personal ( and on call 24/7 and apparently ) than most shrink . all the while and more and more death occur . what funny be and just a the first disappearance and the more best bud vanish and the less the rest care . sure and they give a few second of air time to say wow and ( that person ) just wouldn not run off etc and but then theyre back to their sexual way . and speaking of which and it probably due to the horrid script and or maybe it be i who be lose interest at minute 30 and but it be really hard to keep up with who like who of the group a they all seem to be sexual partner of the next or someone would either be freak out to the max by another and best friends the next scene . see represent the creepy guy that keep a mouse or rat in his pocket literally and be the most obvious suspect . i be give the film too much credit ( and time and ) but how he become part of the elite 10 i will never know . but and i digress and there a mystery here . why be these kid target . why be virginia think she kill someone and when it be never prove ( till the end ) that any of them actually have be slaughter . and why would the trailer and poster claim these killing to be six of the most bizarre murder you will ever see . hell and even for 1981 and most of these have be show in any of the first two friday the 13th film coincidentally enough and friday the 13th part 2 be release 2 week to the day of happy birthday to me . perhaps and theyre speaking of when they film it month prior and but be late to the and well and party . when the secret be reveal and trust me and you will have to rewind 3 4x to actually get the laughable and incoherent motif and and even then and put the subtitle on to get all the mumble victim or killer word . even if you get the first time and it an unbelievably outrageous and hilarious finale . it almost worth watch the whole movie again and but a a drinking game . this birthday gathering should be avoid . it a horrible and illogical first draft script please and please know it take multiple rewrite before the cameras role and it contain either way under act or extreme over acting and it 100 % unrealistic on how people react in extraordinary circumstance . side note represent when i be a kid and or say 10 11 year old and i love horror film . ( still do and oddly . definite guilty pleasure and but they be get hard and hard to watch a year pass . ) we get our first vcr and and i tap a many horror film off network ( or and edited version ) tv . all i remember of happy birthday to me be get the last 10 minute on tape and which scar me to death and obviously give away the big mystery on who the killer be . even though i have see other clip of this movie and i think this be the first full length view i have have . thankfully and this awful movie do not wind me a a child . i be old now and and i can take this trash . but never again . side note 2 represent that say and that crazy happy birthday to me song play in the end credit ( and a a score throughout ) still creep me out tremendously . i guess and this movie ( or last few minute and ) do have an influence on my childhood . shame on you and melissa sue anderson .
