Now, as for Berlanti, Cephus got one of them. Blindspot is Berlanti as well. There's at least one more and i can't recall what it is off hand. I dont' care who you are, though, you can't be 'the guy' for a 5-6 different shows. You don't have time to even do outlines for that many seasons let alone do scrpts, direct, etc. You need to learn to find the right people to run the shows and be their resource for questions, etc. If he's doing more than that, no wonder they're sufferring. I'd say this year flash is down, Arrow is up, Legends was up, SG about the same, blindspot down a lot. The answer is likely the simplest, he's the glue and there's just not enough of him to go around.
