For obvious reasons, environmental doom is an increasing theme in sci-fi. So much so that the term "Cli-Fi" (with the "Cli" for "Climate," obviously) is an actual thing now. Mark and John dive into it, looking at some of the more well-known examples out there, with some discussion of other instances in sci-fi history where environmentalism has been at the heart of the premise.

Settle in as we review nearly 20 of the best (or at least the best as we see them) death scenes in film and TV. Some obvious ones, some not so obvious ones - and Mark and John's lists are surprisingly different.

It's tick season! We talk our favorite science fiction parasites (and a few symbiotes) in this episode honoring the return of the clingy bloodsuckers. Like James Gunn's "Slither?" We've got you covered. Have you ever thought of the Borg as parasites? We're on that conversation too. Give a listen!

Let's call it the Hank Pym effect - one single choice by one writer making one character kind of wrecked forever. There are quite a few and we talk about some of them in this week's episode.

It's March Madness folks, get your brackets out and pick the winners -- of the best sci-fi movies and TV! Thirty-two "teams" over four quadrants: Cyberpunk & AI, Space & Exploration, Aliens & Horror, Blockbusters & Franchises - all vying for the right to be the one true champion. Who's gonna win? Who's gonna get eliminated? Will there be a cinderella team? Only way to know is to LISTEN to Mark, John, and special guest Robert Heil!!!

For the first time in a decade there's no Star Trek series currently in production. John and Mark take a look at the state of the Star Trek franchise in terms of stories and corporate status, and what we might expect going forward.

Mark and John get into the political once again in an analysis of resistance movements in Sci-Fi on the big and little screens.

There are favorite movies, and there are the movies you wish you could have that 1st-viewing experience with again. Sometimes they're your favorite movies, but sometimes they're movies that just hit you in a time and place. Heck, some of them might be movies you don't even like! Join us for a talk about those cinematic 1st times we wish we could repeat. Ah, nostalgia...
