Yes!! When they first announced it I was like "DON'T HAVE Legends cross with them! Just have Stephen Amell, Grant Gustin, and Melissa Benoist be OnSceen together!" But after hearing Justice Society Of America... FORGET WHAT I SAID, HAVE EMM CROSS OVER!!
THAT Episode he Directed for The Flash, The Runaway Dinosaur, THAT WAS SOOOOOOOOOO GOOD!! I thought Kevin Smith brought A LOT to the Table and I was like "BRING BACK KEVIN SMITH FOR THE FLASH!!" But him Helping Arrow would ALSO BE GREAT.
