I literally just started binge watching on Hulu
and I'm almost through the first season. I'm finding out however that the characters are going to change in the future. The oldest daughter isn't even going to be the same actress after this season and the middle daughter will be changing at some point in later seasons. That's a bummer, I don't like when they change actors. I'd rather they just write the characters off, have them move away or something and they can make references to them, emails they hear from them or making references to just getting back from trips to see them. It is usually weird to bring in a completely different person but act like it is the same character.
I guess I have that to look forward to. Since the two oldest daughters are already out of school (oldest) and on the verge of being out of school (2nd oldest), I'm curious how they keep them as central characters in the show for 6-7 seasons. They should, ideally, move out and have their own lives and families of their own and should probably be fringe characters.
I guess I'll find out.
