The time trials are annoying and the dlc is flawed, for example the dlc just feels like if they mad everything have a green hue then said it's atomic then expected us to actually like that- it just feels lazy and boring. Main games good though. The bosses are fairly fun but once you fight more of them they get boring, especially the hunted ones. The story's also not the best but for this it doesn't really matter since your playing as a shark. I also think they probably should've made the game longer and with a bigger map and more shark skins, overall try it out see if you like it but most of what I'm saying is preference.
