Those who must rely on subtitles should know that almost all dialog is uncaptioned, and what little there is, is out of sync and often appears to be just guesswork of what might fit with little relevance. Thus impossible to follow or understand, and I would request that Amazon refund rental fees. Of course this presumes you might have had an opportunity to watch the visual picture. That almost no dialogue is captioned is not to say the screen is ever empty of typeout. Like all captioning now, instead of simple dialogue subtitles, a continuous flow of IRRELEVANT, ridiculous sound effects, descriptive opinions of mood, tedious lyrics from nearly continuous overlapping, awful background music, or if no lyrics, kindergarten level attempts to describe every background note. A few examples from this film: screeching instrumental music, droning instrumental music, foreboding instrumental music, exciting instrumental music, sad instrumental music, and more, repeated over and over, between bird calls, unidentified animal sounds, beeping, boom, whooshing, sighs, moaning, clinking, squishing, squelching, trickeling, leaves rustling, loud this, soft that, ad nauseum. Apparently to prevent your gaze from ever actually straying from this useless stream of asinine narrative to watch the actual film. From what little I got, appeared could be half-way engaging science fiction, technically well done, good production values, but with, I'm guessing from occasional lip reading, less than intelligent dialog.
