I don't know what show you're watching, but Walter and Hank were great characters. Marie could get annoying and I could see why people didn't like her character, but I think it's meant to be that way.
The villains were great on that show. Gus, Tuco, and Uncle Hector were my favorites. Tuco was a maniac.
I never watch any of these new shows and series on tv, but i made an exception with this one because I got into it. Some of the best writing on TV. Even better than the sopranos.
