I do. It's pretty decent. It does go a bit downhill later on, but I'd say in the late S3 and S4 (I blame it on the show being cut short and having to wrap up everything too quickly).
In the genre of "seemingly a crime show, but really a deep sci-fi", I'd strongly recommend Person of Interest, if you haven't seen it already. It contains what I consider to be, to date, the best discussion of the topic of general artificial intelligence, and all its ethical and safety implications.

It's definitely not big-budget, but there's decent FX in there, just judiciously used. Future tech is impressive, but not crazy flashy.
> (pre-breaking bad quality of TV).
Could you elaborate on that one? I've only seen the first three episodes, after which I gave up, but from those three I thought Breaking Bad is a low-quality and extremely low-budget show.
