According to IMDb users, sci-fi shows like Firefly, Lost, and Star Wars: The Clone Wars were some of the best series during the 2000s.

That changed in 2004, when one massive sci-fi series took serialization to a cinematic level on the small screen, scoring ratings so big it changed everything happening on television, forever.

Hollywood doesn’t take chances like it used to. Back in the 2000s, we got a string of sci-fi blockbusters that were big, ambitious, weird, and sometimes great.
