Finished the tenth session.
Yes, it's not exactly like the original.
No, it's NOT terrible.
The casting is fantastic, the music is on point, the story is predictable (even if you had never seen the anime), but the majority of the important elements are still there.
Spoilers so Beware:
The weakest parts of the show, from what I can tell, are mainly isolated to Vicious/Julia early on. Especially Julia's scenes at the club.
