The Canary episode last season almost felt to me like a backdoor pilot. I personally enjoyed that episode a lot more than I thought I would. The flash-forwards last season were a mixed for me. The first half of the season I really enjoyed the flash-forwards, but they did start to drag in the second half of the season.
I’m open to the idea depending on how it is done. Crisis on Infinite Earths may mess with how the future pans out. There is still a lot to play with on the mythology of the Green Arrow and his team.
