We were discussing the CW shows at the comic shop last night and this point came up.I wonder if Batwoman is being developed as a replacement for one of the existing shows (Arrow?) or will we be seeing a five-way crossover in the 2019/20 season?
Arrow S7
Flash S5
Legends S4
Supergirl S4
Black Lightning S2
Arrow is getting into that sweet spot where if they plan accordingly can end strong. Our discussion was that most sci/fi and comic shows that have lasting impact run 6-8 seasons. Once a show starts getting lengthy(again comic/sci-fi/fantasy) it almost becomes a parody. Our examples were Supernatural, Smallville, Stargage SG*1 and X-Files of went past their prime. Ended strong and well, ST:TNG, ST: DS9, nuBSG, Fringe(5 seasons) and likely Game of Thrones.
Perhaps they stagger or move a show into summer until they end Arrow making Flash the senior show with a few seasons left till they end that at S7/8. In theory if interest stays high as new concepts are put forth, like Batwoman, they could sustain this for some time. I think if he's done well Constantine being spun back into a solo might have interest. Especially if Supernatural ever ends, it'd be a thematic replacement.
Our discussion of possible new characters we'd like to see introduced or explored keeping with B/C list characters were:
Question - either version
Captain Atom - military angle allows cosmic possibilities, f/x similar to Steel
Swamp Thing - ecology/nature themes f/x could be similar to Ragman
Resurrection Man - outlier due to the varied tones and themes it could explore. Someone said "he's too out there" but most agreed at this point nothing is off the table.
Zatanna - magic based show w/guests Constantine, Blue Devil, Deadman etc from time to time.
Booster Gold was ruled out being too similar in concept to Legends but he's a favorite in that group.
