I wasn't a huge fan of Tuco in BB. He worked as a character that lasted the length of time he did, but I think I would've got tired of him had he been around longer, and I didn't get why people seemed to rave about him so much after. So when the first episode ended with him, my first thought was, "ah fuck, really?"
The desert scene made me a bit more optimistic though. It played up to his character - paranoid, savage, not as bright as the best - absolutely perfectly. And they seem to be going to utilise his brother (?) as much as, maybe even more than him, and he seemed interesting.
Jimmy bartering with Tuco was hilarious.
