"The science fiction genre has always been financially successful. When you look at the box office numbers, you begin to realize that some of the biggest contemporary releases fit within the genre. Even if you ignore the superhero genre, you're still left with movies as gargantuan as Avatar: The Way of Water, Jurassic World: Dominion, and A Quiet Place Part II. These movies sell tickets, but unfortunately, not every entry in the genre is that successful.
This remains true when you venture back to the past. Again, you have some undeniable classics, but as is the case with every genre, there are films that simply go unnoticed. That's why this list exists.
Below, you'll find ten science fiction classics that unfortunately fell by the wayside. These movies offer just as much quality as their blockbuster brethren, but they sadly failed (and perhaps continue to fail) to ignite the world."
