I really liked the show for many of the things you mentioned. I recommend it every now and then to friends or coworkers because I haven't met a single person yet who's seen that show. Very underrated.
My only gripe was that it seemed in season one, they tried a bit too hard to add drama to the show to appeal to a broader audience that isn't that interested in the technical stuff. Especially Joe Macmillan just felt over the top and just not credible at times. They made up for it in season two though, adding a lot of back-story for him and making him just more consistent in general. But even then, season one is still the best imo.
