When I first popped in Happy Birthday to Me, I checked the timer to see how long the film was. I was amazed at the length. Both animated and horror films share a common ground: attention span of the selected audience and that should be at or right around 90 minutes. Anything more, and you'll lose the bulk of your audience.<br /><br />This 110 minutes, or 20 minutes past its prime was a huge problem for me. I'd like to say half of this movie could've been edited out, but I would be too generous to say that. Go ahead and watch it and tell me how many scenes could've been edited, even without being a film major.<br /><br />Regardless of the overstayed visit, the movie was below mediocre. It spent all of its time trying to be this huge mystery on which of the "elite 10" is killing off the remaining friends. For the most part, they not only over-do it, but they zoom in on a face and pretty much say "It's this guy! No! It's this gal!" You'll spend more time with the camera misleading you than actually enjoying the movie. And don't get me started on the acting.<br /><br />Okay, that got me started. I had to laugh in the beginning trying to remember if Melissa Sue Anderson played the character that went blind on Little House on the Prairie (later, research proved my suspicions correct) because all the way through this movie, she genuinely looked blind. Strange, as an established actress, she should've been the best of the group, but turned out the worst. The rest of the staff, aside from Ann (Bregman) was pretty damn bad, too, but she, uh, took the cake.<br /><br />The movie begins with a group of ten friends, and one's immediately killed off. Barely anyone thinks twice of this "dear" friend's disappearance, so they continue on their merry way. Slowly, then more rapidly, there are revelations about Virginia's (Anderson), the main character, past and her psychologist, who's a tad bit more personal (AND ON CALL 24/7, apparently) than most shrinks. All the while, more and more deaths occur.<br /><br />What's funny is, just as the first "disappearance," the more "best buds" vanish, the less the rest care. Sure, they give a few seconds of air time to say "Wow, (that person) just wouldn't run off" etc, but then they're back to their sexual ways. And speaking of which, it's probably due to the horrid script, or maybe it was I who was losing interest at minute 30, but it was really hard to keep up with who liked who of the group as they all seemed to be sexual partners of the next or someone would either be freaked out to the MAX by another and best friends the next scene. SEE: the creepy guy that kept a mouse/rat in his pocket  literally  and was the most obvious suspect. I'm giving the film too much credit (and time,) but how he became part of the "elite 10" I'll never know.<br /><br />But, I digress, there's a mystery here. Why are these kids targets? Why is Virginia thinking she's killed someone, when it was never proved ('till the end) that any of them actually has been slaughtered? And why would the trailer and poster claim these killings to be "Six of the most bizarre murders you will ever see"? Hell, even for 1981, most of these had been shown in any of the first two Friday the 13th films  coincidentally enough, Friday the 13th Part 2 was released 2 weeks to the day of Happy Birthday to Me. Perhaps, they're speaking of when they filmed it months prior, but were late to the, well, party.<br /><br />When the "secrets" are revealed, trust me, you'll have to rewind 3-4x to actually get the laughable and incoherent motives, and even then, put the subtitles on to get all the mumbling victim/killer's words. Even if you get the first time, it's an unbelievably outrageous and hilarious finale. It's almost worth watching the whole movie again, but as a drinking game.<br /><br />This birthday gathering should be avoided. It's a horrible and illogical first draft script  please, please know it takes multiple rewrites before the cameras role, it contains either way under acting or extreme over acting and it's 100% unrealistic on how people react in extraordinary circumstances.<br /><br />Side Note: When I was a kid, or say 10-11 years old, I loved horror films. (Still do, oddly. Definite guilty pleasures, but they are getting harder and harder to watch as years pass.) We got our first VCR, and I taped as many horror films off network (or, EDITED VERSIONS) TV. All I remember of Happy Birthday to Me is getting the last 10 minutes on tape, which scared me to death  and obviously gave away the big mystery on who the killer was. Even though I have seen other clips of this movie, I think this is the first full-length viewing I've had. Thankfully, this awful movie didn't wound me as a child. I am older now, and I can take this trash. But never again.<br /><br />Side Note 2: That said, that crazy "Happy Birthday to Me" song played in the end credits (and as a score throughout) still creeps me out tremendously. I guess, this movie (or last few minutes,) did have an influence on my childhood. Shame on you, Melissa Sue Anderson!
