My take on why some fans seem to be disappointed with his films--
I believe I've finally come to understand why it is that so many of John Carpenter's fans seem to be so disappointed with him and his films time and time again. While I am certain I am not the first or last who has come to this most obvious conclusion, but as I said for me, personally, I have figured out what I believe most likely to be the issue.
I know my love for Carpenter started with the film so very many horror fans fell in love with, and remain in love with.. John Carpenter's Halloween 1978. And it was that film that introduced me to John Carpenter. The film is the reason why I have loved Carpenter, and IMO, I've now come to see that the film with which John Carpenter became the legendary horror icon is actually not at all what Carpenter is about, nor is the infamous film at all what Carpenter seems to enjoy creating and directing.
Clearly John Carpenter's heart and soul belong to the genre of Science Fiction, and his involvement in the creation of "Halloween" allowed Carpenter to have a career in Hollywood and with this great achievement he began to make the movies of which he'd dreamed of making..the movies that he loved to see.. The movies that John Carpenter's true heart and soul belong to..Science Fiction.
If you really look at how Halloween came to be and Carpenters involvement IMO, its really easy to see that the main core of ideas, and structure for that horror film WAS NOT from Carpenter, but rather Yablans who came up with the core concept and ideas, to which Carpenter and his girlfriend, Hill further fleshed out into characters, and details thus becoming the movie so many of us came to know and love as, "John Carpenter's Halloween".
This clearly was not what John's heart and desire were longing for in once having broke into Hollywood his continuing in the same horror vein as the "slasher", Halloween(obvious due to his Sci-Fi creations that were to follow). He used that great opportunity that got his foot in the door as merely a stepping stone into getting to make the type movies that HE wanted, that HE was interested in, and what HE, himself, his whole life long had loved going to movie theater's to see... Science Fiction!
I admittedly am not a Sci-Fi fan, not even in the very least, and usually avoid Sci-Fi like the plague. But it is exactly this genre of Sci-Fi that the infamous director of Halloween loves to make, create, and bring to the "big screen". And IMO, due to that fact it leaves fans similar to myself who fell in love with Carpenter strictly due to 1978's Halloween, its left many of us disappointed with Carpenter's films time AND time again. They're nothing like Halloween and in fact are in a whole other category much different than the type of horror of Halloween. I recognize that there are also many fans who love both genres, horror and sci-fi alike, and IMO, those fans seem to not be the ones who've found themselves disappointed time and again with Carpenter's movies post-Halloween.
While there is absolutely nothing wrong with Carpenter's love for Sci-Fi and he may indeed be a master in that genre, but IMO, the reason for the overwhelming disappointment that seems to plague him time and time again..movie after movie is because of the fans that love him because of Halloween, a genre of movie that it appears as though Carpenter does not enjoy, or desire to make, create, and bring to the big screen. Yes, that particular type of horror movie gave him the opportunity to make the films he does enjoy, and I believe I now have come to understand that I can love Carpenter for all he gave us in Halloween, and respect his love of Sci-Fi and understand that its exactly that particular genre that Carpenter will most likely continue on in.
Again, I realize others may have long since clearly understood these above described reasons for the disappointment many fans have had with Carpenter's films, but I, personally, am just now coming to understand why it is that I, as a huge "Carpenter fan", have found myself so often disappointed with many of his films.
