Funny you should mention The Unit. I discovered a couple weeks ago that it was now on Hulu. I had favorable memories of the show, so started watching it again. I'm into Season 2 already.
I must have gotten in on the show in later episodes, because of the ones I've seen so far, they're pretty bad, except for the very first one. I compare it with Miami Vice--seems pretty cool at first glance but the plots and action are laughably unrealistic, just downright silly. I'm hoping it gets better.
Meanwhile, I'm also re-watching (on Hulu) NYPD Blue, which I also enjoyed back in the day. Now up to the middle of Season 5 (of 12). What a first-class, superior show that was. Good plots, good dialog, great acting--a first-rate police procedural set inside a first-rate soap opera (or maybe vice-versa). I've now seen over 100 episodes and not a bad one yet.
I also re-watched on Hulu all 6 seasons of Justified. That was another superior show I can recommend highly.
