Reddit, what is the worst movie you have ever seen?

I am currently watching a movie called Arachnoquake. Pretty much, it's about a bunch of fire-breathing giant jumping spiders released in New Orleans after an earthquake. Yes, fire-breathing spiders. They literally killed the 'Queen' spider by shoving a bomb up It's ass. For a movie that was produced this year, the effects are awful. The spiders look completely computer generated. The spiders in Arachnophobia, a movie produced 22 years before this one look more real. I really don't know how a movie this bad even got released.

So I ask you Reddit, what horrible movies have you seen? And what about them was so bad?
