I personally like emotional romance animes but I hate animes where there is this many sad moments. I liked the anime a little at the beginning but as it progressed I started to dislike it because of the story and the way it was taking place. There were parts that I hated for how they did so I looked up the saddest part of Kanon and I watched a youtube video with tears in my eyes and dropped it without a second thought. Then I came back and thought to myself " what if I watched the whole story" so I went back and read a summary for every episode and I am glad that I did not watch it I would of hated those sad moments but this is specifically MY opinion some people love sad moments and watch anime for that reason its just that I can only handle a few.
