I just started binging on this one recently. Man, it is pretty fucking good. Best ST I have ever watched, IMHO. Season three tells one long story with a few side episodes. It was great. I poo-pooed this show after watching the first two or three episodes back in the day. I think I decided that I would give it a few years before I would watch it again, because that was generally how long it took every other ST show to get interesting. Then it cancelled in year 4. Well, let me tell you this is a great ST show.
However, once I am done with this last season, I will have watched every minute of ST in existence.
