But if 60% of a show's season isn't good, that's probably enough to merit a lack of faith in the season as a whole?

Every time I see Mirror Master I read Music Meister and I just want NPH to reprise the role in live action so we can get a musical episode (or crossover).

I'd rather they keep Ward the Big Bad than rehash the "enemy from within" storyline they've done…what, every season now? First Ward, then Bobbi/Mack, then Andrew. I get that it's a spy show, but this has gotten more tired for me than a persistent(ish) antagonist.

Because the window has pretty much already closed. CW turned it down once already, they were the most-rumored network to be picking it up before that. Constantine is dead, but Matt Ryan as Constantine has at least a shot of living on in Arrow and maybe (just, maybe) LoT (and I guess Flash, too.)

FWIW, I bought an indoor antenna and got it installed and running in ~ 5 minutes.

I will just say, I think it's a bit of a stretch to say the dramatic stakes were thrust upon them. They had to work with them, they knew they'd be working with them from day one, but they couldn't really plant the seeds of them that most shows can because doing so would provide possible spoilers for a major, expensive…
