Jimmy Corey's books and the TV series based on them have both gotten a fair amount of acclaim -- awards attention and the like -- but not nearly enough, imnsho. The show had a good first season, but it's only gotten stronger in season two. If it keeps on at this level, it deserves to be ranked among the best SF shows of all time. Acting, directing, writing... and my god, the look of it. The space stuff, in particular.
BABYLON 5, FIREFLY, and the various STAR TREK successor shows were all spiffy looking in their day, but THE EXPANSE is to those shows as they were to the original TREK, and as the original TREK was to ROCKY JONES: SPACE RANGER.
Speaking of Rocky, though, that is the one thing EXPANSE lacks: Pinto Vortando.
