The Leprechaun
The Leprechaun horror film series' sleeper is Leprechaun 4: In Space. Yes, it is set in space, but that is precisely what makes it so mind-numbingly fantastic. Leprechaun 4 is an excellent illustration of how to convert a completely ludicrous idea into something really "unique." The film is jam-packed with realistic effects, innovative killings, and hilarious Leprechaun lines that will have you rolling on the floor. Leprechaun 4: In Space is a must-see for fans of the Leprechaun franchise or horror films in general.
Pinhead
Hellraiser: Bloodline is an intriguing continuation of the series that also acts as a precursor to the events that have come before. The narrative jumps between three distinct eras, beginning in the 1700s and ending in the 2200s. My anticipation for the fourth film in the series was not very high, and if we're being honest, I'm really just here for Pinhead and the other Cenobites. Seeing Doug Bradley live is always a treat because he never loses that chilly, menacing, and demonic air that he exudes throughout his shows. This is illogical and difficult to understand, but who cares about any of those things? Pinhead's moments in Bloodline are so horrific that you should see the movie even if you have watched everything else in the Hellraiser or any of the other works that Clive Barker has created, then you definitely need to check out this one. Even if there isn't a whole lot of logic to it, it's still a great fun ride all the same.
Critters
I must confess that I was curious when I learned that Critters 4 would take place in space. How, after all, could they beat the previous Critters films? The cast list, though, made it seem less promising when I looked at it later. Darren Dourif? Does Angela Bassett? Anders Hove, a well-known actor from Denmark? Simply put, I couldn't see how this could possibly work.
When I eventually watched Critters 4, all of my worst concerns were realized to be true. The plot was poor, the characters were terrible, and the environment was a terrible rip-off of other brands' settings. When viewed from the standpoint of a fan, it is especially disappointing since the very elements that made earlier installments in the series distinctive and interesting have either been eliminated entirely or are simply not there at all. The fourth installment of the Critters series is a shambles and a major letdown.
Dracula
Dracula 3000 is an almost unwatchable awful horror movie. Dracula 3000 (link here) irritates me. Even though it's terrible throughout, the finale left me dissatisfied. "Dracula in Space" was so horrible it was dreadful, not excellent. Fun notion, but terrible performance and language. If you want a bad day, watch it.
Also, Coolio. It stars Coolio. Did I mention that?
Jason Voorhees
The most notorious horror movie sequel to take place in space is called "Jason X." Jason Voorhees is the real-life embodiment of the horror movie myth and legend. It doesn't matter how he got into space, but he did. Nobody really cares about the reason why he's in space. The only thing that counts is that Jason is out in space and ready to cause mayhem.
In my view, Jason X is worth seeing for easter eggs and nods to past Friday the 13th movies, as well as his metamorphosis into Uber Jason.
Although this film isn't for everyone, aficionados of campy, cheesy slasher flicks will like it.
