I just picked up this DVD because it had English subtitles on the Japanese disc in my local rental shop. I had never heard a thing about it, nor could I even read the DVD box cover, so I was going in with an open mind.
The film starts quite slowly, and goes down a well worn path in terms of plot, (it's basically a hostage situation where the abductor and abductee have planned it together to get back at the abductee's father) and I didn't think much of the acting at the start, though all the main players seem to warm up as the film proceeds. I had this film pegged as nothing special, filler material until the titular g@me actually began, at this point the film really starts to show some nice ideas (nothing amazingly original, but slickly executed). It's quite drawn out toward the end, but I went from thinking nothing of the show to being pretty impressed. This deserves to be seen by more people, I think anyone into twists would certainly enjoy it, and it offers a little something to think about in comparison to the current crop of summer Blockbusters.
Overall an enjoyable couple of hours, I want to give it 6.5, but 7 is too high, the guy is a little too cool toward the girl for how he is supposed to be feeling. The acting isn't outstanding by any means either.
