This series will literally change your view on life and help you understand what is really important. With light comedy and heavy hitting emotional scenes, this is a must watch slice of life anime that tackles real-world fears and difficulties. I laughed a few times and cried a great deal. As someone with depression and anxiety, I will give a fair warning to those with similar conditions. If you are not prepared, it will affect you to the extent that your body is in literal pain. Do not binge watch it like I foolishly did and watch it a little at a time. Please be very careful as you watch it and be mindful of your own health. Aside from that, this is one of the most beautiful anime I have had the pleasure to watch and it makes you really feel for every character. I highly recommend watching from the first season. I also recommend the Kyou/Ryou and Tomoyo alternate stories to help you understand the last actual episode of After Story and why things seem to restart. This anime is based on a fantastic game and those with knowledge of it easily understood what happened at the end of this anime. If you are confused at the end of episode 22, there are many explanations online or by other reviewers here. There is a very good explanation in the comments section of episode 22 on KissAnime. I don't do spoilers. I hope you get as much enjoyment and see the world differently after watching this series as I did. Enjoy the beautiful story of Clannad and the struggles of Tomoyo to protect what matters most.
