My favorite recent animes are FullMetal Alchemist:Brotherhood, Ao No Exorcist, Tiger & Bunny, and Shingeki no Kyojin. Summer Wars was also an amazing film.

If you haven't checked out Shingeki no Kyojin, (Attack on Titan), I strongly recommend it. It is only 6 episodes in... but man.... it is just amazing. Brutal, emotional, epic, best anime I have seen since Brotherhood.

Some other animes that I love are as follows:

One Piece
Naruto
Trigun
Tengen Toppa Gurren Lagann
Cowboy Bebop
Gintama
Code Geass
Chuunibyou demo Koi ga Shitai!

and Dragon Ball Z is in it's own category.

Since I don't know what style of manga you like here are some of my favorites:
Gantz,
Cage of eden,
Bakuman,
Death note,
naruto, one piece,
Rosario+Vampire,
Bloddy monday, Fullmetal Alchemist
And many more (lol). If you have an ipod or ipad, you can download: manga reader, you can just browse through all the manga in there (yes everything in there is free :D) Anyway I hope I was helpful! *Epic brofist*
