This list didn't come easy. Anyone who's seen even a minute of Breaking Bad will know how mind-bendingly awesome it is, but a good show is only as good as its characters. And there are loads of great characters in Breaking Bad.
So – what criteria have I actually used to rank them? Good question. I'm not even sure I know, but if pressed I'd say it's the ones that made the biggest impact – not always the ones I liked the most, but the ones that have stayed with me – that have come out on top.
Oh, and two more quick things before we get started:
1. There are some minor characters who don't make this list (these tend to be the functional ones that don't really have much depth or definable character). So if you're reading this and you're that ginger bloke who played the character that works for Saul whose name I can't remember... sorry.
2. There are horrible, horrible spoilers everywhere from now on. If you haven't seen every episode of Breaking Bad, stop reading this now. And get on Netflix.
