Everything about this was literally perfect. The dynamics of Berry and Iris, Harrison, Cisco, Kaitlyn, and ESPECIALLY his fathers. All of the actors are some of the best I've ever seen in my life, and The CW managed to make each character realistic and provides an authentic experience to their dialogue, the way they react to their environment, circumstances, and past. Harrison's acting and the way he carries out his plans are literally bone-chilling when he reveals them to the rest of the StarLabs team, and there are many instances of this and it all wraps up with one of the best seasonal conclusions I've ever experiences. The plot fluidity and pacing stay consistently amazing the whole time, which makes it truly worth the 9.9/10 rating.
