I did only listen to season one. Story was interesting, the action was just noise with very little information to indicate what was happening; I think sometimes there were robots, I feel like there were more explosions than any underwater situation could handle, the 'smartest people' weren't all that smart, etc. I know that without bad choices, there is no story, but I didn't know enough about the characters to truly follow their bad choices and the consequences were lessened simply because it wasn't clear what was happening during the action sequences - though it was pretty easy to figure out where the actual story was going.
