I must admit, series like Breaking Bad, Walking Dead , Boardwalk Empire , True Detective are all pretty slow , almost introspective alot of the time (you know, it feels like the characters are staring alot, thinking alot, looking into the distance alot, getting way to philosophical every 2nd conversation ) . Breaking Bad also did not work for me at all when i initially tried it, S1+S2 felt like a slog and i stopped.
I then got back to it much later because i wanted a series where things were somewhat slow because i was doing alot of late night work/projects ..and for some reason it got me hooked that way. S3+ they definitely had this thing where every episode would end on a cliff hanger (despite the actual episode only moving along at a snail pace). Eventually it felt like there was way too much happening in the last 2 seasons, which was strange.
Same thing with the Walking Dead, i still haven't gotten into it, but i can see the draw based on my experiences with Breaking Bad. I think you really need to be in a situation or a specific mood for these types of series. I sometimes think these series work well for people that are distracted alot (work/kids/ipads), and you can miss a few minutes in every episode and still know pretty well what is going on, even the recap aka "previously on..." in these series is like 1 minute long and is all you need quite often...especially if you know the characters.
This is why True Detective Season 2 was a total disaster for me....it is a slow series, yet somehow they sneaked in so many plot holes in between all the philosophical conversation that i never knew WTF was going on. I just did not have the patience and concentration levels to watch the season in that way....that's when i rather then just watch a more "down to earth" type of series which gets to the point.
Speaking of another series on this list, if you haven't tried "Better Call Saul" , then get it. It's a type of prequel to Breaking Bad. Season 2 should be coming out anytime now. I think it's a bit less moodier than Breaking Bad, so might even be a good start if you struggle with BB.
