The show is definitely entertaining. Good job on the scenes and settings. Great to see attempts at creating the atmosphere of palaces of the 15th century Peninsula and inclusion of monuments like Alhambra in some scenes.

The cast delivered an unequal performance through. Sometimes over-stressing an emotion. A bit too much dramatisation.

If you don't get bothered by lack of historical accuracy then you'll enjoy Isabel very much. However, in my case, I found the narrative leaning to one side only with Muslims being the villains and Jews the allies of the Catholic Kings who are often portrayed as merciful and generous. History tells us a different story: the Granada War was vicious. Innocent victims on both sides of the conflict. The Nasrids while they didn't share the same faith as the Catholics were just as Iberians. Both Muslims and Jews suffered a great deal during the war and afterwards. The list goes on.

All in all, it's a good entertaining show worth watching.
