Cuz markus said the Alien theme would be better dark and I agree. In fact, I think a lot of this site would be better with a dark mode, so I revamped the themes I just revamped with dark mode compatibility.

Refresh your page if you haven't already, then check your dropdown menu for the Dark Mode toggle setting. Note that I've only tested the movie-based themes, but give it a whirl and tell me what you think (try desktop view as well as mobile/resizing).
