I can understand why people say Clann[ad is sad but what I don't get is why people make such a fuss about it. In the end of the anime the sad parts didn't even matter and I didn't shed a tear anyway lol.
Yes I did cry, no shame at all. Especially the scene where Tomoya was remembering Nagisa on the train to which she has passed away at this point was a real, i mean REAL tearjerker. I think I remember Ushio started crying as well, it was too sad with the background music playing as well.
Note: I watched this 4 years ago, so my memory is a bit hazy, but the emotions are real.
