The worst deleted scenes in films are simultaneously the best because it shows that the filmmakers had enough awareness to recognize their mistake. Then again, some of these embarrassing scenes cut from sci-fi movies are so bad one has to wonder why they were ever even shot in the first place. Of course, deleted scenes exist in all genres, but science fiction relies on such careful nuance that scenes edited out of sci-fi films can easily save a great movie from becoming a terrible one.
Some of the greatest sci-fi films have, indeed, been saved by this foresight. Movies like Ghostbusters, Alien, and various Terminator installments have all been rescued at one point or another by someone realizing which scenes absolutely could and could not make it into the film.
Whether it be deleted scenes deemed too violent for the screen or odd filmmaking decisions, these omitted scenes changed their films forever. Here are deleted scenes from science fiction movies that would have left their films with a big black eye. Some spoilers are ahead – but only if you've been living under a rock for a decade or more.
Blade was actually a pretty entertaining comic book movie, not least of all for its kick-ass action, including the epic final fight. The battle culminates with Blade defeating Frost by kicking a syringe full of deadly vampire poison into the guy's head. As the poison seeps into his body, he explodes.
However, there was a deleted scene in which his death was a little more drawn out. The CGI in this scene was just awful, something they had avoided despite their relatively small budget up to that point. They made the right choice to leave it out.

Towards the end of Alien, there could have been a scene in which Lambert was frantically working in a room occupied by a xenomorph that she somehow failed to notice. She does finally notice it, however, when the alien (clearly a guy in a suit) crab-walks over to her and slowly rises to its full height in what's supposed to be a menacing fashion.
It fails to achieve menacing, though and succeeds in looking supremely cheesy. Had this scene been in the film, it would have stripped all the terror from this beast Ridley Scott spent so much time making terrifying.

This deleted alternate ending to Terminator 2: Judgment Day could have looked a lot like the dreaded 19 years later scene of Harry Potter – but would have been even worse as it would have deconstructed the logic the entire story.
In the scene (which takes place in the future), an aged Sarah explains that John Connor fights a different kind of war as a Senator because the war with the machines never happened, avoided by their actions in the past. There's just one problem: if the war never happened, John Connor wouldn't exist. Kyle Reese would never have come back to impregnate Sarah because nothing would have driven him to travel to the past. Good thing someone caught that before they included it in the film.

For some inexplicable reason, a deleted scene in Terminator 3 attempted to explain where the design for their Terminators originally came from. In this scene, we meet Chief Master Sergeant Candy, a Southern so-and-so with a distinguished military career despite being a total doof.
As Schwarzenegger mouths his lines with a hammy dubbing of this crazy accent, the movie immediately ceases to be a sci-fi thriller and becomes a wacky time-traveling adventure. It's a mercy that this scene was left out because it would have undermined the entire tone of the film simply to answer a question no one was asking.
