For this season both Arrow and Supergirl have 100% positive on Rotten Tomatoes as compared to 85% for The Flash. Of the negative reviews: "It's possible all this time-traveling and rewriting of history is beginning to wear thin, and even the writers can no longer keep it all straight." "After a promising start, last season turned into a depressing muddle. I'm hopeful that now that the timeline has mostly been reset, season 3 can have a fresh start, but this wasn't an inspiring beginning." Haven't seen Supergirl yet, but a did like the Arrow season premiere more than the Flash premiere. And I didn't really like Arrow last season.
