I've never played To Be Continued, but I love Astounding Tales 2ed!
It has a lot of pulp larger-than-life characters like Doc Savge, The Shadow, etc... Huge list of other heroes and villains.
It handles dinosaurs and other animals, cars, airplanes, zeppelins, rocketmen, weird science, zombies, Lovecraft horror, robots, Nazi science, Victorian adventures, comic book WWII, sixties spy romps, "future" pulp, etc...
It can also handle a lot of figs. I've played a game where 5 players had ten miniatures each with no problems.
I doubt you'd be disappointed.
