To start with the summary is wrong bcz this special isn't about Makino's parents going to NY or the rest of it, this special was released after season 2 to introduce the final movie and it also includes a mini performance by the Arashi boys so this is like a promote to the movie. At the beginning, There were the moments where F4 and Makino were toghether yet there wasn't actually a story to talk about but u get to see the characters all over again, i believe that itself worth the watch! U need to watch this before the final movie, if u already watched the movie then there's no need to watch it bcz like a said it's between the drama and the final movie.
