While there are plenty of hits that fans are familiar with, there are some that might’ve slipped under the radar. These movies might not have been box office hits and have mixed reviews, but they are still entertaining to watch. Some have gone on to gain cult followings since their release, showing that some fans find them great films in their own right.

10 Darkman (1990)

Darkman movie

Where To Watch: Can be bought or rented on Amazon Prime, YouTube, and Vudu

Liam Neeson has been in a lot of films and has so many memorable roles that some might’ve forgotten about this underrated gem. In Darkman, he plays a scientist named Dr. Peyton Westlake, who is working on a new type of synthetic skin to help burn victims. After his girlfriend finds an incriminating document about the mob in their city, he is beaten and burned in acid before his lab blows up. After some radical treatments, Westlake now has enhanced strength and can’t feel physical pain, but at the cost of him becoming mentally unstable at times.

Leave it to Sam Raimi, who wrote and directed the film, to create a very compelling character who is the perfect mix of man and monster. The movie makes sure to build up Darkman’s character before and after his transformation, but manages to do so without sacrificing the action that viewers want.

9 Coneheads (1993)

Coneheads SNL movie

Where To Watch: Hulu

A sci-fi comedy that is based on the Saturday Night Live comedy sketches of the same name. After their ship is shot down, Beldar Clorhone and his mate Prymaat settle into life on Earth after learning a rescue ship won’t pick them up for seven years. They have a daughter and live a relatively normal life while waiting. However, they have to deal with INS agents that are trying to find out the truth about them.

It’s a pretty good comedy movie with some sci-fi elements to it. Plenty of familiar faces from Saturday Night Live appear in Coneheads, from cameos to supporting roles. While it received negative reviews upon its release, it has since gained a more positive reception.

8 The Iron Giant (1999)

The Iron Giant movie

Where To Watch: Tubi TV and Hoopla. Can also be bought or rented on Amazon Prime, Apple TV, YouTube, and Vudu.

The Iron Giant has gained a cult following, but didn’t receive much attention when first released. Hogarth Hughes is a 9-year-old boy that lives with his single mother, Annie, who discovers a giant 50-foot tall robot in a forest not too far from where he lives. He befriends him and a friendship develops between the two of them along with Dean, a junkyard owner who lets the Giant hide out there. However, the U.S. military and government are looking for the Giant, and Hogarth, Dean, and Annie's lives are flipped upside down.

The movie has its light-hearted and comedic moments, but it also tackles some heavy topics. Hogarth explains the cycle of life and death to the Giant while Annie deals with being a single mom after her husband was killed during the Korean War. This movie doesn’t shy away from its mature themes but keeps it simple for a young audience to understand.

6 A Wind Named Amnesia (1993)

A Wind Named Amnesia anime movie

Where To Watch: Crunchyroll

A Wind Named Amnesia is a post-apocalyptic anime movie about a mysterious wind that blew all over the world and wiped out most of humanity’s memories, along with basic things like speech and civility. The movie follows a young man named Wateru, who travels the world after he was found by a man named Johnny, who taught him everything before passing away. Wateru encounters a mysterious woman named Sophia and together, they set off to see what’s become of humanity.

It might not have flashy action scenes, but the movie is a pretty good watch. Seeing how the survivors of the wind are living is interesting because most of them are now resorting to barbaric ways, with some sacrificing others to appease a higher power. Some have even been brainwashed by a supercomputer. It’s an entertaining movie that has some typical post-apocalyptic tropes, but also has some twists and turns to keep viewers watching.

5 The Astronaut's Wife (1999)

Jillian, Spencer’s wife, begins to suspect something happened after he starts exhibiting strange and rather aggressive behavior. But it might be too late for her to run now that she’s pregnant.

The Astronaut's Wife is a sci-fi thriller that has a strong resemblance to Rosemary’s Baby. Overall, the movie is a little predictable and has some classic sci-fi and thriller tropes, but it’s an entertaining watch nonetheless.

However, he finds out that the suit isn’t the only thing that came to Earth and must decide if he wants to be a hero or not.

Though targeted towards children, Star Kid has a pretty sweet story. Some of the special effects will look a little outdated now, but that shouldn’t stop viewers from seeing this underrated gem.

2 Fire In The Sky (1993)

Fire in the Sky movie

Where To Watch: Hulu

Fire in the Sky is a sci-fi movie about six loggers who run into what looks like an alien spaceship on their way home from work. When they stop to look at it, Travis gets out of the truck to get a closer look. After it appears he gets zapped from the mysterious ship, his friends leave out of fear until Mike pulls over and goes back to find him. Only Travis isn’t there anymore. The five friends tell their story to the police, only to be scoffed at. After a few days, Travis mysteriously returns, but it seems like he’s changed.

It has some suspenseful bits and lets viewers see first-hand what Travis went through after his disappearance. The scenes are a little disturbing, though not graphic. The movie doesn’t shy away from showing the aliens and what they look like.

1 Alien Resurrection (1997)

Alien Resurrection Ripley 8

Where To Watch: Amazon Prime

Set 200 years after the third movie, scientists have created a clone of Ellen Ripley using her DNA and mixed it with Xenomorph DNA, naming her Ripley 8. However, Ripley isn’t the only clone that was created and the Xenomorphs were recreated. After they escape, Ripley and a group of mercenaries must survive them as they try to escape.

Some sci-fi fans might overlook Alien Resurrection because its predecessor, Alien 3, is pretty underwhelming when compared to the first two movies. However, this sequel should not be overlooked. Ripley 8 is a little different from Ellen Ripley, being a more sarcastic and dark-humored heroine. Seeing Sigourney Weaver play a familiar yet different character adds a little nostalgia, but keeps both characters from being the exact same.
