Having never read the books nor played the game, I did enjoy this series for the most part, especially the first two seasons. Originally, the story featured a Witcher that fought monsters. It was full of magic, a little lust, and a budding romance. Then in season 3 the focus was 100% on a war. No more monsters (okay, maybe one monster). No more lust or love between Geralt and Yen. And with very few exceptions did we ever get to see much of a glimpse of this supposed power that Ciri has...which was the basis of the series to this point, wasn't it?
Again, I have no history with the story/lore, but it does seem as though the shift in focus made this a completely different story than how it began. Maybe that's why Henry wasn't happy and left. Don't get me wrong, I enjoyed the journey, but even I could tell that this was a little off the rails. This season finale was a big let down. Episode 6 was the high point of season 3, so I started off watching this second half with high hopes. Then the utterly boring episode 7 happened, which made me worry about episode 8. And yeah, I was correct. It was not the great send off I was expecting for Henry's departure.
