It's way more interesting than before, more spread out rather than focusing on one group. One noticeable impression is that sometimes characters interact in a way we don't know the "background" of. Char A interact with B about X because of Y, with the X and Y we don't know of. Tho, the interaction between characters are good and personalities are great, so it doesn't really matter (this impression is already there since 2nd season, but not as much). All in all, the conversation are more unique/diverse this way and kept interesting, even if you don't really get the connection.
You can expect the same as prev season, with above aspect being the special one.
