Bullet review:

+Great character development for Nautilus and some other characters. Wave is also a welcome addition to the cast.
+Benthos was a pretty effective villain.
+Getting to explore the Water realm was interesting and I liked seeing their culture.
+The nuance of Benthos' backstory. Even if he is an obvious villain, you can still totally see why he turned out this way.
-Some of the writing, particularly Benthos' monologue near the beginning, felt very unnatural and forced. This really could've used some work.
