The best part of Clannad After Story are the alternative cycles at the very end. Frankly I found the sad parts of the series too much to bear. I am soft hearted and that side of anime at times is way over the top IMHO. First series was decent.
I am watching Full Metal Panic ....how many times i have re watched this i long lost count of. It surprises me how strong the line art is in these, they are really quite basic in art style but the story remains decent..if a bit overly influenced by the feeling of interest that that time in American military matters. The story is sweet and I still hope to see the overall story finished in Anime form.
I am going to re watch Welcome to the NHK next! that will be fun.
