Just did some reasearch and you hit the nail on the head.
Phantom's ending is 100% Kuroda's idea,or to be exact the result of Kuroda's convictions.It does have Urobuchi's endorsment even if he doesn't share those convictions (beginning to wonder if he has any ).
He even says this:
In an VN the end is a result of choices, the end is a sort of reward for the choices made.In an anime the end is predetermined, the difference of medium explains the difference in endings (...) with the principles we had fixed for ouselves this was the only ending possible.
It's interesting he says that because in the VN you can make the same choices as in the anime and get a different ending, which means he hadn't fixed himself any principles when writing the VN.
Yeah, finished all of game of thrones, it weirdly started to remind me of Shiki with how due to having so many characters you'd have a cliffhanger at the end of an episode and then in the next episode you'd follow other characters without getting any answers to the cliffhanger!
As for Barakamon it wasn't even on my radar,I'll watch an episode at some point and tell you.
New job + broken laptop + a bunch of other family issues means I haven't watched any anime in a month (that's a first for me since 2010) , haven't seen any game of thrones either (I've miraculously avoided spoilers).
I'm hoping to get back on track in a couple weeks and Gaworare is one of the shows I plan on marathoning.
