I just finished Breaking Bad, second run-through. I had first started watching it when Season 4 had just started; binging seasons 1-3 and followed it episode-by-episode after.

I was surprised to notice that the content I binged stayed with me much better than the seasons I watched one-episode-at-a-time.
Also… Holy shit. Breaking Bad gets dark towards the end (Jesse getting imprisoned and forced to cook for months; his ex-girlfriend getting shot). I had forgotten all about that. I had forgotten almost everything about the last … 4-5 episodes.

The scenes that had stayed with me the most from my first watch: Box Cutter's throat-slicing scene, the Prison Shankings, Hank vs. the Cousins, Hank's death scene, Gus's death scene.

But, seriously, rewatching it reminded me how good of a series Breaking Bad is. I couldn't help but binge the entire rewatch marathon. It's an incredibly intense experience.

In the context of what happened to Game of Thrones I'm also very happy to see the consistent quality and execution in Breaking Bad's storytelling. It's a series that set out to tell a story. The story makes sense from beginning to end, and gets resolved nice and tidy.

I'm a little disappointed we don't get to see more of what happens to the family while Walt is gone. The trial etc, that all seems like potentially interesting stuff.

On rewatch, I noticed my sympathies changing. I have a lot less sympathy towards Walt, even very early on. Knowing some things in advanced completely changed my view on him; whereas on first watch I rooted for him quite a bit.

My sympathy towards Skyler also flipped. On my first watch, I disliked her a lot at first, but grew to like her when she "went dark". On this rewatch, I disliked her less and sympathized more with her, though her behaviour beyond season 4 became incomprehensible to me.
I like Marie a lot more this time around as well. She's still pretty unbearable when it comes to shoplifting and generally the way she talks to people; but I hadn't realized just how much she loves Hank. How much she supports him through his PT (despite how atrocious Hank is specifically to her). Knowing Hank's death was coming, my heart broke into pieces when I heard their last phone call end in "I love you. // I love you too.". Hearing her say "He isn't picking up, probably because he's in the thick of it".

I don't think I even noticed anyone's grief the first time around, most likely because I was dealing with my own. Hank's death was a shock then. This time, I knew it was coming, and I had a lot more time to process how people felt about Hank before and their reactions to the news.

Just a bunch of random thoughts about that series. I usually only rewatch "comfort series" such as comedies, animated series, etc; I very rarely rewatch epics (except that I used to re-marathon GoT before a new season). But I don't regret giving Breaking Bad a full rerun. It is such an intense experience; during Seasons 3&4 I yelled in my pillows a few times on credit roll, just from the adrenaline.

You too should give it a shot.
