Truth be told, I haven’t watched that movie either.
I don’t even know if I am even going to watch it anyway. From what I have heard, it is not that kind of Hollywood blockbuster that I like the most (it isn’t even from Hollywood!), it is just as hard to understand as Evangelion itself, and in general just doesn’t worth the time. In this sense I am even worse than Saki, because I simply do not care.
The thing is, Saki didn’t actually care about the movie either. She only cared about the person who cared about the movie, so she tried to enter the movie world just to have another common topic with him. She saw with her own eyes how happy it was for Wataru to talk about the movie with someone who “got it” – in this case, it was Nagi – and she wanted a happy conversation with Wataru, so she tried to understand the subject.
It is almost amazing just what a common topic can do to two people. I have always considered the relationship (platonic relationship, before I am murdered by certain shippers) between Nagi and Wataru rather volatile. They actually seemed to enjoy bickering and disagreeing over everything. Yet when it came to a movie that they both loved, they acknowledged each other to be a fellow fan and they openly shared their love of the movie. For the period of this chapter they appeared to be such good friends that we can mistake them for having the right chemistry.
Saki herself definitely sees it this way, as she became jealous of Nagi. She went as far as bringing up something (to the readers) that nobody cares about nowadays: the arranged marriage between Wataru and Nagi. I am not entirely sure if this engagement has been cancelled, but even if it hasn’t, it doesn’t seem like either Nagi or Wataru were serious about it as they both had their eyes set on someone else. Saki seems to have proved just how insecured she was by bringing up something like this in her mind.
The one really good thing about the relationship (romantic relationship, as I am expecting passionate hugs from certain shippers) between Wataru and Saki is that they were very open and honest toward each other. Wataru never meant to ignore Saki in order to make himself look “cool” (although sometimes ignorance happened due to sheer stupidity), and Saki did not try to cover herself with “dignity” by being a Tsundere. Their good wills and deeds for each other were always there to be seen, by both the characters themselves and by readers.
In a sense, Wataru and Saki are an ideal couple, as they spend their time and resources in reaching out to each other for a better understanding and a better relationship. Time is not wasted on meaningless guessing games, misinterpretation of words or unintentional flirting with any third parties. If someone is truly your “life in itself (sparkling!)”, you simply do not waste time on any other things.
Except a movie that you love, maybe…
