I loved it so far. It's like Breaking Bad once it hit its stride, plus he doesn't have an annoying wife and kid. When I watched Breaking Bad I skipped every single wife, son, dad scene. Don't feel like I missed a thing.
Probably the best show on TV for me now, not saying much because after Arrested Development and Breaking Bad were gone I haven't watched anything (Archer has become really bad unfortunately). So bring on more Saul, can't wait until the next one.
