the only thing I can really say that was bad about this movie is that the storyline was messy, it was a bit difficult to keep up but maybe the fact that there are no eng subtitles is also apart of the reason. overall i wouldn't say it's a bad story or movie in general, I in general love plots that a goofy and really random but I know not everyone does and so I understand other people don't really like it. but the story did make sense to me at the end

(!SPOILERS AHEAD OF THE WHOLE MOVIE!)

from what i understood of the movie is saimon has a really big imagination and likes takashi, then they go on a trip together, and takashi falls in love with a woman who he met because of a phone number in a bathroom who ends up bieng an alien, but before they find out she's an alien saimon confessed his feeling to takashi, but after they fought with the alien lady, takashi and saimon go back home, and then they stop to say bye to eachother but that's when takashi asks saimon for the juice that they got from the thug lookin guy on a bike, and saimon throws it at him but the next shot is saimon standing there alone and the can falling on the ground and no takashi anywhere, and then we see another part of his imagination and that's the end

so overall very confusing(i could barely explain and it still doesn't make really sense)
