All I have to say is that this anime is the most amazing one I have EVER seen in my life! It is second only to Clannad~After Story which is amazing as well!
It literally took my breath away and left me crying over the sad, touching, and bittersweet moments! Clannad also has a lot of comedic scenes that left me laughing or rolling across the floor of my bedroom! I DEFINITELY recommend this anime to everyone in the world out there because:
1.) It is extremely touching and beautiful.
2.) Teaches you about the importance of family and friends.
3.) Teaches you about goals in life and life itself.
4.) Sends powerful messages.
5.) Will leave you with a different view about life once you've finished.
6.) Is another reason really needed?
Anyways, there is (to me) absolutely NO excuse to not watch this anime at some point in your life if you are an otaku or at least like anime! You have to watch it and I guarantee you will at least tear up at some point in Clannad or After Story. That is how amazing this anime is! Wish you a happy watching!
* Tip: Have a tissue box near you while you watch both seasons! (I needed it...)
