Love Hina was okay, but it had a really bad ending...
If you're looking for some emotional stuff, maybe you should try out Clannad/Clannad After Story from Kyoto Animations.
Maybe you should check out some older animes such as "Trigun", "Cowboy Bebop", etc.

If you're in for a dark atmosphere, you should check out "Garden of Sinners", it's series of 7 movies, but the story is rather complex and it's a bit gorey.
