I usually avoid reading reviews until I finish. However, by E5 I had increasing doubts because the story felt a bit choppy and was losing me. So I checked out a few reviews and one mentioned it doesn't get good until E7! I pushed through to E7 and yes it gets 'better' but that's in part because of an increasing curiosity to find out whether the writing would improve.

Key story points would pop up and then oddly characters wouldn't mention them until much later.

Anyway, I did find the characters and the story in the last five episodes engaging but was disappointed many rough edges weren't fixed before this went into production. I don't fault the actors or the production quality, but suspect the problem is with the script and likely the direction.
