i will say this, slave route book 4 felt like they had no idea what they wanted to do, and it ended up feeling like we fall upwards to the results. everything happens at random, we have to do this for that, and then something diferent happen, than out of nowhere we are sent to an island that feel like a side story, then more nonsense, and then we are back in that island, but now its important.
and then it ends.
korra doesnt even feel like she is developing(or breaking depending on how you look at things). she just sudenly goes, alright, i guess im a slut now...
i think this writter's block came from exactly that development, to me, they should've taken a month between routes to chart the main points of the story they wanted to tell.
it also doesnt help that LR started really strong, and managed to make korra a better character(even compared with the SM). but because they didnt do that, they fell to that trapping again, this time due to not knowing what to do to keep the momentum.
sorry for the long post. its just that, i can feel how much love they are putting into this project, so it pains me to see them doing such minor mistakes that snowball into massive trappings like that.
