I'll be honest, the show has remained largely episodic so far. But that isn't a bad thing. I'll make this short:
Art: The art in this show is absolutely incredible. Colors are trippy, vibrant, and stand out. Character designs are flawless and a treat to look at.
Sound: Equally interesting techno/jazz soundtrack that in no way takes away from the experience. Watanabe continues the trend of top-notch soundtracks for his works.
Story: As psychedelic, funny, and nonchalant as it's main character, Space Dandy. Stories don't go too deep, but are usually jam packed with crazy, sometimes logic-defying stories that combine humor with a bit of gold old Bebop-style action and some self-ridiculing satiric "fanservice" that says a lot more about the industry of fanservice itself (on purpose) that the overall quality of the show itself.
Overall:
Hilarious (the English version is even funnier, more culturally aware, and better flowing than the Japanese version), beautiful to look at and listen to, and a real ride from start to finish. No direction or overarching story overtly detectable so far, but honestly, none is needed.
