Being completely open here: skip the books and watch the show. I would not have continued this series if I wasn't already invested in the characters.

What I liked: the ending battle. Bellamy and Wells as brothers. The ships.

What we could deal without: Glass and Luke. The fact that a lot seemed to happen off screen. The lack of depth 99% of the time.

Again, there were too many characters and too much world building to happen in 1000 pages.
