So i got three series started from the new season, most of which i have no real idea about:
Magi 1 - A different take on the whole Aladdin/Alibaba tale with a shounen twist to it. Quite nice and nothing to hard to get into. Will definitely watch at least the next episode or two of it to see how things go.
Jojo's Bizarre Adventure 1 - The only one i had heard of before this season started, but even then only little. I love how it kept that manga vibe with the sound effects being shown as they would in manga when used. The story is pretty good too, and even though it did feel a little quick for a first episode, it wasn't overly so. Also, it took until the end of the episode for it to really click that it's based in England.
K 1 - I'll be honest, i'm still not following everything that went on in episode 1, so it's really hard to properly judge how this was. Animation was top notch, but i'd like a bit more explanation behind everything, which i'm hoping i'll get when the second one airs this week. It looks like it has potential though, so we'll see.
