I mean its tough to know if the writing is bad (it probably is) or not just because its tough to know the character like Wendy. On surface writing her as a kid makes sense, but is it a kid or a computer, and is it behaving like a girl should or like a homicidal machine. So I'll give them some slack on at least her writing just because the character could be all over the place.
Some of the other potentially bad writing could just be the 5d chess that Kirsch is playing. Example, while watching I thought it was retarded we are to expect one of the richest people in world's fortress of solitude is so under manned and insecure two of their biggest projects just walk around the complex with a dead body, and a invading force of 15 people can just walk around freely, until I realized Kirsch orchestrated it all as a setup.
So yea...not great writing still, but the show to me is best thing we've got in a long time for TV so I'm giving it a pass.
