I really liked the first two seasons, but I stalled out part way through the third. I may have just needed a break though, as I had been really enjoying it and watching the episodes fairly quickly. I do want to finish it sometime.

I was also impressed by the pretty accurate representation of the technologies that I had familiarity with. The things that I don't know much or anything about also seemed to be presented in a plausible way, or at least much better than the average show.
