For me, I didn't find anyone in To Sleep any more likable than anyone in Fractal Noise or find any of the concepts interesting enough to stick around. And I couldn't even get on the space adventure angle because Soft Blade is such an overpowered piece of equipment there's no tension in anything that's going on with Kira and we don't know enough about the rest of the galaxy to care if the Sith blow up Taris. Even if you cut out the filler, I don't think the set up stands.

Not to say that Fractal was much better, but at least it was humans in a (stupid, pointless) dangerous situation over a Superman.
