Perhaps my biggest problem with this movie were my high expectations due to a few reviews I read which highly appraised it. In my opinion the story, the core of which exhibits some potential, is its main flaw. Shallow, non-developing characters, missing plausibility, incoherent dialogs and confusing plots are disguised behind artsy (admittedly quite nice) sceneries, wonderful music and post-futuristic-combined-with-retro aesthetics. Which per se is not a problem, but it cannot substitute for the missing parts of the whole product. I understand that a low-budget sci-fi movie is a great challenge, but then again not every challenge must be taken. I have seen a fair amount of other low-budget sci-fi productions (e.g., from eastern Asia) with amazing performances, non-existing props, but excellent stories (notably with a philosophical extension). At least there the movie makers did not constantly flood the scenes with blue color, lit-up close-ups à la "It is time for my close up mr DeMill" and floor smoke like discos back in the 80's...
All in all, it is a waste of time unless you happen to be a huge fan of the Flash-Gordon or "a trip to the moon"-by-Georges-Melies type of movies and if you don't care about script coherence. The generous four stars are just for the atmosphere and the music.
