All Flash had to do was care about and place focus on the leads. The actual leads. If the show was focused primarily on The Flash, West-Allen and the Flash family, and the lore of the superhero and his speed force and saving the world and universe, it would have been amazing.
This is why I will always side eye EW because not only did he try to destroy the WestAllen bond but also the Wally/Barry relationship (I don’t care about Joe so he can kick rocks) but the relationship between Barry and the West siblings truly was meaningful.
