That. WAS. FCKIN. AWESOME!
Seriously, what a finale. It was a wrap up of five years (maybe 10 if you include the flashbacks which will no longer be there), and ended with a bang.
Normally id say theres no way they all died (the caged one surely dies regardless, and they couldnt have saved Earth2 Laurel right?), but then its a comic book show so who knows. (likely that the underground prison thing is close by and Slade lead them there in time?) But one things for sure, they have a great cliffhanger for next season which is ultimately a new start for them.
Black Canary vs Black Canary, Nyssa vs Talia,, Slade f'n Wilson just being a badass in general and of course Arrow vs Prometheus being more about Oliver vs Chase.
Chase was fantastic. Its a shame to see him go because hes easily the second best villain (if not top) this show has seen.
This was an amazing season overall with a fantastic finale. S2 is my fav but I think this one is above s1 now. It went back to basics and it worked.
