Was it the girl's daydream? Or is it me? (spoiler, maybe)
I left the movie sure, that what we saw was completely the day-dream of the woman. I mentioned it to my wife almost in passing - I thought this interpretation is pretty obvious - and was surprised to find she disagreed, and another friend as well. So I wonder if I am completely off or what.
My main reasons:
-- This explains why they don't speak; they don't need to since he (being imagined!) and her (imagining) trivially `know` what each other thinks...
-- While I'm not exactly an abused, frustrated housewife, I think that the best thing about the movie was to get to see this terrible life. And somehow I think that dreaming of such a cute `prince on a black motorcycle` would be very appealing to such persons. Together with a lot of guilt feelings of course, which explain why the adventure also turned bad in several ways - his random accident killing a woman by the ball, they being caught by the boxer and then by the police... And the fact that the daydream concludes by her serving her husband while `cheating` him with the invisible `hero` is very tragic...
-- This also explains many other things which are otherwise completely unrealistic, like the fact he was never caught (until with her), the fact he has this fancy motorcycle and education, his lack of sexual aggressiveness (a likely daydream for an abused wife!), and of course all the super-powers he `obtains` in prison ... of course, another explanation is that the movie is not a realistic one.
I'm not saying a movie has to be realistic. But I think the basic message of the movie, against wife-abuse, is even stronger with my (daydream) interpretation.
What do you think???
