@srol the best thing I can say about season 2 is that for a couple episodes it had ICE as the primary antagonist; the acab part was cool
I think most of the praise season 3 got was relative to the first two seasons, and if it had opened with season 3 it would have gotten a pretty lukewarm reception; it's the kind of thing I would watch on a plane if there weren't any movies I wanted to see
