I'm confused by what other people are saying...
It seems that I see this movie in a completely different way than others. People were actually expecting answers in this movie...answers for what? Suicide Club was beautifully explained, you're not supposed to be confused or have questions after watching Suicide Club. There's no ''investigation'', or ''suicides'' (like the guy in the restaurant was saying, there's no ''Suicide Club''). If we're only talking about Suicide Club, the suicides are just a metaphore, or an exageration, of how the media, marketing or trends are affecting society and brainwashing people, causing them to lose their personnality, therefore dying inside. You just have to imagine that suicide became a trend, and everyone followed it, that's the exageration. Also, all the schoolgirls had cellphones, or everyone listened to the same damn music (dessert), that's a way of telling us that everyone is the same, no one has a ''self''.
But after seeing Noriko's Dinner Table, I'm confused...
This movie wasn't at all what I expected. To be honest, I was surprised that there was a sequel, because the first movie had already answered all the questions. One thing's for sure, while watching this movie, I was continuously telling myself : ''OMG, no one in this damn movie is connected, they're all in the Suicide Club''. And I expected one of the characters to finally wake up, but I don't think anyone did, or maybe one did... By accepting Kumiko as their mother or wife, Noriko and Tetsuzo were still deep in the Suicide Club, they completely lost their identity, even if Noriko knew she was Noriko. Yuka is the most interesting character in my opinion. I think that in the end, she wasn't yet fully connected to herself, but was on the right track. For example, she said that everyone looked like a lion to her, and she was a rabbit, meaning she is different from everyone else, she has a ''self''. And so she severed her ties with her family members to go do some soul-searching. And the soul-searching part is important, because saying you are different, that you are yourself, doesn't necessarily mean that you are connected to yourself; *self can be a concept that you conveniently borrowed under the logic that it would endow you with some sense of strength (a bit like what Noriko was doing throughout the movie).
*Thanks to Metal Gear Solid 2 Sons Of Liberty for this last sentence, haha =)
In the end, this movie isn't a ''sequel'', this isn't Suicide Club 2, this is Noriko's Dinner Table, just a little side-story. It's like a Resident Evil game ^_^ When you watch this, you're not watching a movie, you're watching what Sion Sono thinks about life, which is why he's a genius! In Noriko's Dinner Table, the suicides are also an exageration, the girls just do it because everyone else does, because it's kool, and people seek fake familiy members because they are super alienated by the Japanese lifestyle. Well, I hope you understand me (^o^)
