It's been bad from the start, and being a DC homer, it makes me sad. The CW strategy is introducing new characters via saturation bombing, so many interesting characters wasted trying to cover up the shitty writing. I foolishly got my hopes up about the JSA when it was teased at the end of last season, dunno what I was thinking.
It's really jarring when you compare the CW stuff to Shield, where they are much more deliberate when they bring in new characters. I've never cared much for Ghost Rider, but he's been awesome on Shield, and really fits into the season meta plot quite well.
