The actors who play Crystal & Gorgon are very bad. Their storylines are also the weakest by far, just plain filler.
It does look cheap, and tbh even Karnak power, which looks quite decent, is a bit off from his actual power in the CBs, which is weird.
But yes, on your last points, it IS better that AoS’s start (and yes, VERY low bar ) but the story is compelling enough to make you want to check out the rest.
It could’ve been a great show with tighter writting and better production… the show really needed more money and more time, but sure, it ain’t the worst crap ever, I’d still rather watch that than Arrow or Supergirl =P
