Hope you have fun.

Ctrl+F "Skyline" not found.

Have people forgotten about Skyline already? It's not even that old.

Dracula 3000, also I think the worst movie ever

Birdemic is kinda sci-fi

Yeti: Curse of the Snow Demon - It's not really a SCI-fi movie but it is so bad that you won't feel the need to watch bad movies ever again. Story, acting, CGI, plot holes, line delivery - you name it, this movie has it all wrong.

Nazis at the Center of the Earth. Can be quite disgusting, but at least you get to see a low budget Robo-Hitler.

Every movie they air on Syfy

Cowboys & Aliens
The "plot" is absolutely horrible.

moontrap

And we have a winner for worst of the worst

Space Mutiny

• Sharknado
• Sharktopus
• Mega Shark Versus Crocosaurus
• Mega Shark Versus Giant Octopus
• Mega Shark Versus Mecha Shark
  And the list could be go on... XD

My vote would be the unholy abomination that was the 9th Hellraiser movie. Here's the snippet from Wikipedia:

In 2011, a ninth film was released to a single theater in California for a crew showing that was ostensibly open to the public. Hellraiser: Revelations is the first film not to feature Doug Bradley as Pinhead and was shot in two weeks for $300,000. It was suggested by Bloody Disgusting that the film was only shot so that The Weinstein Company would not lose its rights to the franchise before it could produce a more profitable remake of the original. The film was released on DVD on October 18, 2011.

The original Fantastic Four movie would probably also qualify, but it can't actually be watched since it wasn't really released.

Ghosts of Mars is immediately the first film that comes to mind.

Surprisingly it was directed by John Carpenter.

Unsurprisingly Ice Cube was an actor in it.

Meatball Machine and/or Tokyo Gore Police. Fair warning: both contain ridiculous amounts of gore.

iron sky. if you go past the first 10minutes you can handle more than I do
armageddon, the core, starship troopers
special mention to A.I. as the most boring movie I've ever watched to the end

Outlander (2008) - it's vikings versus alien. A bad movie, but entertaining. I especially loved that viking beer explodes like gasoline.

This one. Complete and utter shit.

Mosquito

Maximum Overdrive 'When asked why he hasn't directed a movie since "Maximum Overdrive," Stephen King responded "Just watch Maximum Overdrive."'
Rubber
The Human Centipede (First Sequence) and it's sequels.

A mediocre short sci-fi movie

FLESH GORDON!! It's Soooo Bad... It's Good! http://en.wikipedia.org/wiki/Flesh_Gordon https://www.youtube.com/watch?v=mcKvjVsYILw

The best sci-fi movie I've ever seen - Aliens vs Avatars
