Since I have found a blog post on Kyoto Animation wanting you to cry, here is my take on it.
I have only watch 2 of Key’s works (which have really good story line, music, and animation.) Clannad (2 seasons) and Kanon remake, I have to say that it did make me sad, but did not make me a emotional wreck. As you already know, Key’s stories have always been tragic, but at the end, they are still masterpieces because the way they tell the story. These stories are supposed to develop your emotions and also have a bigger impact at the end of the story. If we go though only happy moments, it’s not going to teach you anything. A person have to go though a time of sadness to become stronger.
Does Kyoto Animation and Key wants to take over the world and make everyone a emotional wreck? No… but I do recommend watching any of Key’s adaptations (AIR, Kanon, Clannad,etc.) who are interested in romance, school life, or slice of life anime to check it out, you won’t regret it!
Note that Kyoto Animation make other adaptations other than Key’s stuff… ¶
