Clannad the after story
One of the most beautiful anime, and TV shows that I have ever seen.
The story takes place right after the events of the first season with Nagisa and Tomoya now being a couple, and now delves deeper in to the story of the illusionary world.
The story is well written with character development being amazing as every character let alone the main characters each have their own separate arcs to help you understand them more.
I myself can admit that nothing has ever made me damn near cry let alone cry but this series did just that and helps you understand the quality of family and friends. The ending is the type to leave you there wondering. Dafuq just happened? And having you question many things.
For an anime based off a visual novel, it is what I believe to be the best anime ever created. (the opening theme Toki wa Kizamu Ota by Lia is amazing as well)
i give this an overall of 10 and suggest that you watch it through. careful as if you are too sensitive get ready for waterfalls.
