The budget for this must have been astronomical (no pun intended). I'm guessing they used a lot of harnesses and other practical effects stuff to make it look like the actors were floating in space, and that and the CGI were quite well executed. Editing was also super solid with very cool and creative transitions. It was a pretty and interesting drama to look at. The sound design was also good and the music was nice. But for how well that all of that was done, the script was the exact opposite. Boring, badly paced and riddled with unlikable characters with iffy morals. And when I say unlikable, I mean UNLIKABLE. I didn't like Eve, I **especially** didn't like Ryong, I didn't like the control woman back on Earth, or the dude Eve had something going on with. I didn't like the twin sisters or Ryong's girlfriend's father and ex-boyfriend. At the point where I dropped the show, the only characters I felt for were Santi (the sole non Korean in space) and Ryong's girlfriend. That girl deserved better than her horrible father and indifferent cheat of a boyfriend. I couldn't give a toss about anyone else, and at almost the halfway point, if a show still hasn't managed to make me care what happens to its main characters, then I'm just wasting my time.

I’ve deleted my old comment because I think I gave away too much about the ending. The Trakt app can’t hide my comment, even though I had the spoiler button on, so I could still see my full text. That’s a good reason to delete it.
