Why, oh why do they remake old movies?

Here's the scoop, I jes' sat through the worst movie I've ever seen, and I've seen some pretty shitty movies in my day! The worst thing 'bout the whole thing was that it was a re-telling of the classic horror flick, "Halloween 2", starring Jamie Lee Curtis and the late Donald Pleasance. It's the continuation of the events occurring from the first "Halloween" movie.
The original "Halloween" came out in 1978, and the second installment came out in 1980. It continued the tale of murder and mayhem wreaked upon Haddonfield on Halloween night by Michael Meyers on his quest to kill his estranged baby sister, Laurie Strode. Jamie Lee Curtis played the part of Laurie, and even donned a wig that resembled the hair style she had in the 1978 movie. Those first two "Halloween" films were brilliant and helped Jamie Lee earn her title as "the scream queen".
Then somewhere along the line, the direction of the "Halloween" series veered of the trail with some stupid-assed Irish Halloween masks, that when worn reduced one's head to bugs and snakes when some flashing pumpkin appeared on a TV screen. Pure shite!!!
Then jes' for old time sake, they brought back 'ole Mikey Meyers for the next run of shitty films, weakly based on the original two films.
Then someone finally grabbed a brain and resurrected the proper story line and made "Halloween, H20, 20 yrs Later", with Jamie Lee reprising her role of "Laurie Strode". However, in this film, Jamie Lee's character has tried unsuccessfully to run away and forget the horror of 20yrs ago with a staged death, complete with an alias and new life as "Kari Tate", an understandably troubled headmistress of a hoity-toity private school in California, with a son and a drinking problem. She forever fears the return of her brother, who will finally succeed in finishing what he started. And voila, he finally makes his appearance. She then goes postal and strikes back, finally beheading him.
We thought the series was done. And it would've been, with a great ending to boot, but they had to squeeze one last movie out and ruin it once again.
It then seemed to have finally died, until some idiot who's name shall remain unmentioned started it all over again with his version of the story. He screwed it over royally.
The first one was bad enough, but the sequel went waayyy beyond ghastly. It was pure shit on a shingle!!! Somewhere, Jamie Lee Curtis is weeping!!!
The story was like a bad acid trip. It had such a poor story line, and totally ditched the original plot. It was butchery. The first installment of this new series blurred the story badly enough, but this one, OMG! I jes' can't put into words how horrid the second one is. I'm speechless, and that is an astounding feat, 'cuz I'm NEVER speechless!!!
I guess I should know better by now that remakes always suck, 'cause I've seen and fallen in love with the original and am HUGELY disappointed when I watch the new versions. I don't understand why these hack-writers feel the need to destroy perfect films with their horrid renditions. If it ain't broken, don't fix it!
But still, whenever another remake of one of my favorite films comes out, I'm compelled to see it, and ALWAYS walk away from the theatre disappointed. I keep hoping someone will produce a new film which compliments the original, rather than slandering it.
I suggest that before you watch a remake of a classic film, watch the original first. You'll never see another film the same way again!
