It seems that they took the best parts of the original and tried to build a story around it. It doesn't work as well though and feels rushed.
The premise makes less sense than the original Roberta arc, and more than once I caught myself thinking, "why are they doing that again?" It all feels like an excuse to let Roberta run around and blow things up. It doesn't work: the point of the original Roberta arc was the element of surprise, but now, when we know who Roberta is and what she can do, the novelty is not there.
The new characters (Fabiola, the American operatives, FARC) are underdeveloped and feel like contrived plot devices. The introspection, so well executed in the original's Japan arc, at times degenerates into a meaningless word salad.
