I was thinking what TV shows were not represented on Crisis, here is what I came up with. The list suprised me in that it is longer than I thought it would be :
Adventures of Superman
Lois and Clark ( this should have been easy as both Hatcher and Cain have been on Arrowverse shows )
Wonder Woman ( this disappointed me the most )
The 1st Swamp Thing show
Anything I am missing ?
