I totally understand you. Better Call Saul isn’t a show that has immediate appeal. You may not even be entirely won over by season one ending. I think for me it helped seeing it over again from the start after having watched 4-5 episodes years ago. It is a show with a lot of nuance and detail which is often picked up on second viewing.
What is unusual with BCS is that it just gets better and more engaging for every season while most shows start getting pretty crappy by season 3. For BCS, the third season is provably when most feel they have started getting really sucked into the show.
