I thought it was amazing, sure it's a tad lower than Breaking Bad quality-wise, but that's to be expected.

Tuco was ALWAYS a crazy, unpredictable psycho-lunatic (as Jesse called him) plus he was very affectionate with his family like with Hector, so it's not really that out of character of him.
I dunno how you can just shut if off for not being realistic, maybe it just isn't your cup of tea, but I really enjoyed it.

Gonna watch it regularly, especially since I was a huge fan of BrBa and Vince Gilligan who I believe is a genius just like David Chase of the Sopranos.
