So now that we’ve gone over the Sci-Fi they SHOULD remake, lets take a look at the other side of the coin. Hollywood has always found plenty of reasons to remake a movie. The special effects are outdated, the original is in French and the primary movie-going demographic (suburban teens who need a place to make out) are barely literate enough to read the title, let alone the subtitles, the actress who was in the original isn’t as hot as the actress we’ve got now…the list goes on.

And, listen, remakes are not inherently evil. Try as you might to insist that you prefer The Thing From Another World, the truth is, when you’ve got your friends over and you want to see someone’s stomach turn into a monster, you’re going to opt for John Carpenter’s The Thing.

On the other hand, there are some movies that are sacred. The filmmaker’s vision was perfected the first time around, and any attempt to bottle lightning again will be as disappointing as an 80s hair metal reunion tour. With that in mind, here is a list of sci-fi classics that should never be remade.

5. Close Encounters of the Third Kind

Leave it to Steven Spielberg to make a movie about benevolent aliens who just want to commune with mankind that is more bad-ass than his movie about evil aliens who just want to kill Tom Cruise and his annoying kids. On the surface, the concept sounds pretty lame: Richard Dreyfuss lives in the middle of nowhere, sees lights in the sky, finds out those lights are driven by the extra-terrestrial equivalent of Gandhi. No one gets killed, no one’s stomach turns into a monster. The end.

However, Spielberg somehow manages to capture the sense of wonder that we all have as kids staring up at the sky and imagining what else could be out there. Although some will say his talent has waned over the years, there’s no denying that his earlier films are true escapist entertainment bearing a stamp all his own. This, along with E.T., are about as close as most grown men will come to admitting they like a Disney film (it’s not a Disney film, but Spielberg made sure to include part of the melody from “When You Wish Upon a Star” in the soundtrack). Don’t tarnish that.

4. 2001: A Space Odyssey

It may be only slightly more entertaining than watching the grass grow, and the special effects that wowed audiences back in the day aren’t all that impressive anymore, but, love it or hate it, this Kubrick film stands alone.

It’s hard to believe it ever got made; the plot is baffling, the dialogue is kept to an absolute minimum, and any studio executive who claims to understand the significance of the giant space baby at the end is a worse liar than O.J. Simpson. Any attempt to return to the material would almost definitely result in failure, with evil supercomputer HAL 9000 being replaced by some sort of psychopathic android, and Justin Bieber making his film debut as the giant space baby.

If that’s not enough, 2001 has come and gone, so they would totally have to change the title. Purists ain’t having that.

3. Blade Runner

In the age of CGI, it’s hard to believe that a film released in 1982 could be more visually stunning than most sci-fi flicks these days, but here you go. Ridley Scott adapts Philip K. Dick’s novel Do Androids Dream of Electric Sheep? into a future noir classic that combines believable special effects, exceptional set design, and hey, check this out, a great story with some serious philosophical implications. There simply isn’t any other director who can match the vision of Scott.

Plus, Daryl Hannah makes for a pretty hot robot. Like I said, the film is visually stunning.

2. The Terminator

If anyone ever gets it into their sick and demented mind to “reboot” this classic, I promise to go all Terminator on them, building a time machine so I can go back to the 80s and kill their mother, just for the hell of it. The franchise more or less took a nose-dive after Terminator 2, which wrapped up the story rather nicely. The subsequent sequels and that mildly disappointing TV series (sad when anything with Summer Glau involved is disappointing) have not lived up to James Cameron’s original vision, but things will only get worse if we start from the beginning again. Arnold Schwarzenegger is the only man who gets to deliver the line “I’ll be back.”

1. Star Wars

Now, honestly, does this one even need an explanation? Although, in a way, it is more of a fantasy adventure than a science-fiction film, it has enough sci-fi elements (spaceships, laser guns, Mark Hamill) to justify its inclusion.

The sad thing is, given his behavior with the franchise in the past, no one would be a bit surprised if George Lucas himself suggested a remake. But seriously, you just don’t mess with someone’s childhood like that. That’s like going back in time and molesting Christmas, and that doesn’t even make sense.

What other Sci-Fi movies do you consider un-touchable by any director or studiio?
