Sayonara Jupitâ

Despite the violent efforts of interplanetary eco-warriors, a plan to 'ignite' Jupitar to serve as a second sun gets repurposed when a black-hole is discovered drifting into the solar system. I'm generally quite forgiving of Toho Studios' sci-fi outings but this ridiculous, overly-long and ultimately tedious 'space epic' is awful at many levels. The apparently multi-national cast is amateurish, the writing is plodding and derivative, and the pacing abysmal (notably when the Jupitar-hugging cult leader stops the story in its tracks to warble out some horrible greenie-ballad or sing a 'sayonara' to a heroic but dead dolphin, (also named Jupitar)). The characters are as bad as the actors playing them, and the final reel burns through a lot of time with the endless and sappy demise a couple of characters whose most interesting contribution to the film is a trippy zero-G sex scene containing enough nudity to suggest that the producers thought that the film would actually appeal to adults. Many of the special effects are accompanied by pretentious theme-music and the imagery is full of rip-offs of/tributes to '2001: A Space Odyssey', 'Star Wars and, most egregiously, 'Jaws'. Not surprisingly for a Toho film, the miniature work is quite good (both imaginative and well executed) as are the shots of Jupitar with the best sequence being one in which an exploratory ship skims over the surface of Io, which is 'realistically' depicted as a sea of lava. At over two hours, the film outstays its welcome by at least a third (largely due to beach scenes featuring the new-agey saboteurs and the alien spaceship sub-plot, which unfortunately goes nowhere). Really really bad... but I'm still pleased I finally got to see it (courtesy of the Internet Archive) if only to add to my life-list.

There's no secret anymore, every time there are foreigners in an Asian movie 90% of them are god awful actors and 10% are pretty good but get too small parts. Bye Bye Jupiter is no exception or shall we say worse with 99 % worse then amateur acting and 1% good acting but that is the girl who is naked.

Dr Eiji Honda is on a mission to save humanity to create a new living planet due to earth is getting over populated. But to due that he needs to destroy Jupiter to make it a 2nd moon to march breedable. But he encounters two problems, one a activist group is onboard to sabotage his mission, two a black hole has entered the solar system.

This movie is a big mess, it looks interesting what they had in mind but lacks because of poor choices of cast. A dreadful 3/10

Being a fan of Godzilla, I was interested in this movie because of its director (Koji Hashimoto, Godzilla 1984) and effects director (Koichi Kawakita, Heisei effects director from 1989 to 1997). I appreciate the ambitions of this film, wanting to be a sort of Japanese equivalent of a film like 2001 rather than another star wars knock off like many of the time, and indeed the effects of this film truly are great, I would say on par for the most par with American films of the time. But, sadly, great effects work cant save this shoddy plot. the core concepts seem sound, in the future humans have colonized off world areas, debate among groups on whether it is right to do so, and having to save the planet from a doomsday scenario. But the plot is filled with underdeveloped characters and motivations, ideas that seem to just drop off halfway through (like the Jupiter Ghost ), and a general vibe of melancholy that never feels earned (in that, characters die so that we feel sad, but they aren't nearly developed enough to where we SHOULD care). I do feel that somewhere in this mess there is a great work of science fiction, and perhaps some day there will be a good film of Komatsu's novel, but as it is, this is just a messy, albeit somewhat interesting, misfire.

I watched it once about 8 years ago or more, i am a sci-fi fan thats why i rented it. To this day i havent seen a worst movie. Ridiculous plot, lousy acting, crappy Ed Wood-style special (d)effects. Steer clear away from this.

This is one of the worst Japanese big budget films I've run across. The plot has something to do with a project concerning Jupiter going horribly wrong and... you really don't want to know. Trust me as bad as you think some of the Godzilla movies and films like The Green Slime are, this is worse, but not in a good way.

This is just stupid, the hippies being the last straw on a short list of reasons to watch, none of which are good. I have no idea why anyone would like this on anything but a technical level since the plot, which I've finally been able to erase from my mind only thanks to years of very expensive therapy. All I remember is that the film seemed to want to be a flower power film but was made by people who didn't know what that was and were 15 years too late.(these people couldn't plot a film even if they were handed it)

This film was suggested to me by a friend who loves it, "saying you'll either love it or you won't, but I think you will". He was wrong.

Trust me, there are better ways to spend two and a half hours, many much more pleasant
