I got the same vibe. The game promised too much at the beginning, and by the end, I could see a little bit too much of the man behind the curtain.
The game has an odd voice. The craziest part of my ending was that siding with the scientist in Edgewater lead to an exclusionary commune that turned most people from the town away, killing them. New Vegas did a good job making it's ideologies reflect the real world in some way. This one left me wondering what the analogy was supposed to be. By comparison, I sided with the anarchist group on Monarch after removing their leader and got a relatively good ending. As a metaphor for actual politics that one makes a lot more sense, even though it fell on the predictable side of things.
I suppose the other big problem is player agency. But rather than the usual problem of too little, you're given way too much. It's hard to tell a story about runaway corporate degeneracy when you can land on a planet and solve the problem to everyone's satisfaction when you have a speech skill of at least 100.
And you're right about the combat. It was competent, but very uninteresting. Maybe a more interesting game could put it to better use?
