If you don't like it, just drop it. As simple as that. I'd say Clannad has a lot of good points that a person with a taste for quality would certainly enjoy, but if neither that nor it's themes appeal to you, then skip it.
Maybe try watching Kanon first? Idk. Pick it up again after a few months. Or not.
Forcing yourself or others to enjoy something isn't good.
Ex: Friend tried to get me to watch Gurren Laguunnaengs, I liked it but it was just so hyped for him and he kept on bugging me about it that I didn't enjoy it. Plus it made me drop it...sort of.
After some consideration, I have decided to lock this thread. I wish to prevent a trend whereby members post solely on the negative aspects of a title, criticizing it without reason.
