I thought this could be one big post seeing as Arrow and Supergirl have bricked in terms of posts, but The Flash and Legends of Tomorrow get numbers on the boards Plus the big crossover between all shows is happening. Add to that The Flash is doing individual crossovers with all shows. Also, John Barrowman has signed a deal to be a major villain on all four shows moreso Arrow and Legends.
The Flash kicked off Season 3 greatly last night. Let's see if we sustain that momentum.
Arrow Season 5, which aside from the crossovers. starts tonight and I'm skipping this season. Good news, this the last year that the show will flashback to Oliver's five years on the island. Bad news is future seasons will have flashbacks and flashfowards with other characters.
Legends Season 2 sees the team recruit Vixen and hook up with the Justice Society of America.
Supergirl will see the mysterious new arrival AND... Superman himself!!!
