Their A-List characters are off limits since they want to build the movie universe. Flash just happened to be made before the movies were decided.
Is that the reason? Oddly enough then, I bet a SuperGirl movie would have gone better than this series, and generated more revenue, though, they would need a new cast.
I am not sure who is at fault here, is it the CEO of CBS telling them what to write, is it Ali Adler's (producer) attempt to interfere with the writers or are the writers drunk all the time while making the scripts?
The continuity is just blown to bits. Why was it that when superman was "off world", got supergirl's S.O.S, came flying in, got the equivalent of the Vulkan mind meld instantaneously, but then supergirl can't go "offworld", (and notice how her hair is blowing to the side in space?) just screams of someone saying "Nope, we can't have a man save her! We need a woman, writers fix it!"
The scale they showed of supergirl lifting Fort Rozz was laughable, it was like she was the atom.
Then, since they want to make it that kryptonians can't survive in outer space, then, didn't she just kill all those "sleeping" kryptonians? Fort Rozz was damaged when it crashed landed...and why were the other kryptonians sleeping anyway, instead of taking strategic positions around the globe to fight superman and whomever else?
This is why it seems to be some heavy interference going on from the top.
