These days, I only manage to rewatch about one series a year unless I’m convalescing from something, but here are a few series that have made it to the head of the rewatch queue over the years:
Shoujo Kakumei Utena
Escaflowne
Cowboy Bebop
Trigun
Ergo Proxy
Pumpkin Scissors
Zegapain
Zipang
Madoka Magica
Kill la Kill
Gurren Lagann
The Skull Man
Kamisama no Inai Nichiyoubi
Utawarerumono (original series only—the other two are weaker)
