My take on the quality of writing: the setting is struggling to differentiate itself from similar IPs. That's why it feels "in the middle" so to speak and never quite seems to find its own character.
Personally I would prefer if TOW went further into the absurd and the wacky, but then it would be closing onto the Borderlands territory. If they made it even more like space-western, it's the Firefly territory. If they add some woo-woo and horror elements, it's Bioshock territorry. If it becomes too epic, it's a Mass Effect territory.
It feels as if the setting is constantly trying to balance between its various inspirations and never quite finds its own feet. It's not that original of an idea, basically. Tim and Leon were probably talking about it for years before the development started, during the era when few sci-fi games were being made, but inbetween the idea and the launch, god know how many similar games came out..
