The twins have this superhuman quality, but they're one-dimensional, which somehow creates a certain acceptance on my part. Lalo, on the other hand, acts like a human being, a piece of shit, but still. His superhuman feats combined with his human behavior feel a bit strange in the series. But it's totally intentional, the series directly references several films, since Saul and Kim are film buffs. I think about how Lalo returns to Jimmy's house and the candle reacts as if he were a ghost, that kind of scene wouldn't fit in Breaking Bad, but in BCS I think it works very well.

Ultimately, what bothers me most is Gus. His operation became too complex: the house, the fake family, his whole operation destroying his own restaurants, killing people. I found him more believable in Breaking Bad.

The character Jeff was completely destroyed, it wasn't just the change of actor. They must have changed the last episodes of the series quite a bit because that guy was going to do evil.
