Prob the best TV program I have every watch too...best blew me away. Driving my better half nuts but quoting it :) .
Honestly though...not sure about "Better Call Saul" as a prequel. Loved the character (of course!)...but we know what happens to him. For example, if he gets into situations with undesirables we will know that he makes it out ok, thus no tension. Mind you....if its the same creative team from Breaking Bad, I'm sure it's going to be good.
One of my favorite tributes....of course don't watch it if you've not seen it all.
