Weird but honestly I'm just glad I don't experience your guilt trips on this stuff.
I still really enjoy the show, the writing is really great, and I do want to know what happens.
It's just become a bit like listening to a really great song, and then every now and then there's a note that is very slightly off key.
I still get caught up in the characters, but, usually at the end of the show you're feeling a particular emotion because of what has just happened, and then I think' "Damn writers, he's a drug dealer, why am I bothered".
I had much more of a problem with the Sopranos as well, I hope I don't start feeling as put off by Breaking Bad.
