I watched all the CW arrow verse shows. Black lightening was definitely weak from the very start. It definitely benefitted from people wanting to watch because it had black characters but the storylines were weak. The overly preachiness and the corniness of the show were apparent all of season 1. I tried to give all of the arrow verse shows a chance. Arrow was great season 1, half of season 2, fell off until season 5, then fell off again. Flash had a great first season, then fell apart in season 2 and never recovered. Black lightening, Legends, supergirl and star girl were all trash from jump.
I try to give all superhero shows on TV a show but the quality of BL wasn’t there. It was reflected in the writing.
