Can anyone tell me about the Arrowverse, the collection of CW shows based on DC Comics, and if the rest is worth watching? I watched Seasons 1 and 4 of Supergirl, and they were pretty good (with the exception of Winn in the first season, and taking too long to get to Lex in 4). But I know the other seasons have big problems (though I don’t know exactly what), so I skipped them.
