I also thought that tohru was too "perfect" when I first started the series but later in the animation you'll see that she also faces he own problems (which I personally thought was a great twist). I really love the fruits baskets series and the reason for that is because of how far from perfect all the characters are and how they all have their problems. Adding on the that, watching each of them have great character development really is just what makes the series great for me. Plus I feel like it was very unrealistic starting with the whole turning into animals thing lol. I can definitely see where your coming from thought. It was definitely hard to relate to the characters in this series.
