After an average first episode, season three continued to not impress me with this episode. It could be that Spanish episode titles aren't helpful for the show's quality, but that explanation would be a bit too easy, wouldn't it? In my opinion, Vince Gilligan just isn't able to make the most of the situation at this moment. He now has the biggest acting cast up to that point, but the entertainment value is still rather scarce.
Needless to say, Breaking Bad is still quite a good series and I enjoyed watching this episode, at least the first time I did so. For example, the opening scene was unexpectedly hilarious, even though I didn't completely buy Walt's sudden over-the-top anger. After Hank bailing him out and the two having an awkward conversation in the car, we also get to see an awkward conversation between Jesse and his father. But then it's Saul time again and Bob Odenkirk does what he's best at – stealing the show. Exceptionally, this also applies for Jesse who's doing only one thing in this episode, but that's one of the most bad-ass things you can possibly do.
On top of that, "Caballo Sin Nombre" re-introduces two mysterious bald men, one being Tuco's uncle Tio (racist American writers picking the Spanish word for who the character is as the character's name), the other one being one of Saul's – or maybe Gus's – associates. While we don't get to know a lot about these two, the scenes they're in are indubitably the most thrilling ones of the episode and make you want to see more.
Finally, there are two very rememberable moments towards the end: first, the meme-inducing pizza on the roof scene that also includes some well- written dialogs and second, the not-really-encounter between bald Walt, the second bald guy from before, and the bald two guys with the skull boots. Ever noticed that Breaking Bad has more bald than haired characters? Anyway, this is one of the few scenes in which the ever growing Breaking Bad cast is used in the right way, actually also in a funny way as the "Caballo Sin Nombre" comes into play again.
On the negative side, the characters of Anna Gunn and RJ Mitte are increasingly annoying while Dean Norris and Betsy Brandt seem like entirely unnecessary supporting characters. Luckily though, the good parts are predominant in "Caballo Sin Nombre".
