It's good to see they were able to revise the script in time. Apparently all they needed to do was to put the scriptwriter and the author together. But now Aqua needs to overcome his PTSD to be able to act his part, and he only has 2 weeks until the show.
About the OP, the first time I heard it I wasn't a big fan of it, maybe I had my expectations too high after the first one, but it's growing on me and it's now one of my favourites of this season.
The next general thread is going to be this season's OP/ED thread. So look forward to it! I personally really like the ED and it has grown on me a lot.
