No lmao. There's just less filler, and each episode is really dramatic/intense. Orange is the new black's 3rd season was really weak and sometimes they just get caught up in irrelevant plots but season 4 was good. Wentworth has just been more consistent but if you want some humor you'd probably hate it.
I agree though, most of the cast is white and lacks the diversity of OITNB. They do have a lot of Asian representation though.
