Hi, if you've just watched an anime and you're stuck with that empty feeling about what to watch next, then this list may help you.
There are also some movies/series I'll list below.
Bold = I'm pretty sure you'll like it if you like that genre.
Last note: Try not to hype things when you're about to watch something, it usually leaves you a bit dissappointed. Don't try to compare it with other things you've watched, you'll miss a lot of fun along the way.
Attack on titan
Card Captor Sakura
Fate Zero, Fate Unlimited blade works (tv series), fate stay night
Hajime no Ippo (Really good, don't let the early art get down on you)
Hunter x Hunter (2011) (THIS IS A MUST WATCH)
Kaichou wa maid-sama
Jojo's bizare adventure (I only liked the first season though)
Kami nomi zo shiru sekai (I've read the manga)
Kore wa Zombie desu ka
Kuroko no basket (You'll probably like it even if you don't like basketball that much
Mahou shoujo madoka magica
Melancholy of Haruhi Suzumiya (make sure you watch it in the order the director has published it, it gives a more mysterious feeling about the whole anime)
No Game No Life
Frozen (It's pretty good, don't try to judge while you're watching)
The hobbit/The lord of the rings
Wreck it Ralph
The lego movie
How to train your dragon
Will update later
