Season 1 is stellar and I cannot recommend it enough. It's a little slow to begin with, but through episode 2 or so, it grips you and you will not want to stop watching, so maybe wait for a weekend to pick it up. Clever twists, wonderful visuals, and you're holding your breath every step of the way because the show makes it clear that anything can happen at any time. The first season is very well written and works really well as a standalone miniseries, which is a good thing, because Season 2 is pretty darn bad by comparison.
I love Anthony Mackie as an actor, but he really cannot sell Kovacs' character. The entire time, he looks like he's trying REALLY HARD to be a jerk, but you can tell how hard he's trying, whereas Joel Kinnaman just WAS a jerk for basically the entirety of season one. Outside of acting, the writing has gone WAY downhill (character development is heavy handed and flat, dialog is average, and plot is predictable) and the production value went from blockbuster quality to near Doctor Who levels of cheese.
This takes a heavy toll on the feel of the show overall, where I literally could not bring myself to close netflix for season 1, it's a real chore to open Netflix and sit down for a full episode at a time.
4/5 stars because Season 1 is worth the watch on its own, but I really hope that if it gets renewed, they improve a lot of things for season 3, because the current direction of the show is discouraging to say the least.
