Epic second season
I found the first season uneven and even boring at times (though there were good episodes, the most the one with young Rodrigo Borgia which is pure gold) but this second season is a masterpiece. Dialogue, writing, direction and even music get better and each episode just keeps getting better than the previous one. And oh, God, there is so much to tell. It's 17 years in 13 episodes after all (1475 to 1492), and what years! The War of Portugal, Granada, the Inquisition, Columbus... the story was already written. Why the hell did no one make this series earlier? And to think it was all but cancelled before the premiere!
I so hope the rumors are true and they do make a fourth season, even without Isabel.
