Calling all Pretty Little Liars Watchers (Patreon)

I recently reacted to Season 4 Episode 13 and I just found out that this was the setup for a spin off with Caleb called Ravenswood. It only last 1 season and had 10 episodes. My question is do i need to watch it or should I watch it? Just wondering if i need to consider adding this to my schedule. Let me know what you think. Thank you.
