Love Generation - This one is actually pretty down-to-Earth, not too much melodrama. Riko is slightly uber-cute, but she plays it off so well, that you entirely see where the appeal comes from. She's just incredibly playful, as opposed to childlike. Teppei is a well-rounded character, and very subtly played.
All in all, it's a very admirable drama. For some reason, I think I admire a lot of the older dramas because they were establishing the drama genre, they didn't have to compete with anything and could create more realistic plots. Nowadays, dramas have to surpass everything that precedes them, so they try to be creative in their plots--but the realism suffers.
Hanayome to Papa - A drama portraying the love between father and daughter in which later Seji joins in as a man who wants to marry Aiko. This drama had it all, it was funny, heartwarming, and some times even a little bit sad, just not too much.
