Ohh Ashita no Nadja! saw this anime recently ~ quite chill for the most part with some adventure bits there and there, some drama, a sub-interesting romantic sub-plot with 2 twins way too much older than her, both "Convienently" nobles, while completely ignores the 3 (THREE) boys of her age that do have a crush on her in the anime...mix that with the fact that the protagonist all she wants was to re-united with her long long mother, and you get a mildly confusing plot with not-really-impactful thirdiary characters which for the most part doesn't contribute much to the plot or the show in general, yet they take a lot of screen time for some reason...
...the protagonist herself is "kind of" Ok, it's your run out of the mill girl with a very passionate and cheerfuly personality, yet often stubbornly naive in way too many occasions, nothing really memorable out of this anime, the ending felt kinda rushed (despite having 50 episodes to work on!) and quite all over the place.

TL;DR
6+ out 10

Also yes, the flamenco dance-scene was the best.
