I Hated It. I never had a good feeling about Princess Tutu, even before I began properly watching it. When I saw the first episode that should've been my first hint. It creeped me out, but I wanted to give the show a fair try and after a few episodes it was entertaining. However, the second half of the series it becomes dull, boring and even more creepy and scary than the first episode. Ultimately I strongly dislike the anime and would NOT recommend it to anyone. Aside from the major creep factor, another reason I dislike this anime was the romances. I didn't feel any chemistry or love for any of the couple, including Duck and Fakir. I definitely saw a building relationship, but they came to realize their true feelings and Rue and Mytho were the most boring couple ever. They repeated the same thing over and over, basically treating him as a puppet boyfriend.
Overall, I hated the series. It was dull, creepy, boring and the ending was beyond depressing. Worst Anime Ever!!!! Don't Watch It. I Repeat. Don't Watch It.
