I'm upset about how bad this movie is. As an Australian I worry for Australian sci-fi. Much like Occupation (2018), that other awful Aussie sci-fi, the cgi and camerawork was good, but the story, and particularly the script, was unnatural and difficult to bear. Red Billabong may have worked if this were about a reunion of two estranged brothers (no unexplained horror). Or, Red Billabong may have worked if this were solely about two brothers, not estranged, battling an unexplained horror. I'm not kidding, the mish mash of two estranged brothers battling each other and an unexplained horror was just plain irritating. The theme may sound familiar, and others may argue that relationship colour alongside adversity is a common and highly popular theme. I'll grant that, but for me, it seemed that the script had been written by a 13 year old with no real experience of what he/she was writing about. I'm not kidding, there are unrealistic stereotypes, sexism, male bitchiness, horrible initial portraits of young women, loads of cliches, potty mouths throughout, and way too many attempted classic lines. It's awful. At a certain point about 50 mins in a young man with a beanie appears and converses casually with one of the brothers. This beanie guy has appeared from nowhere in the forest, and is not seen again, nor was he seen previously in the movie. I actually clicked on all the pics above to try and figure whom the hell he was! Awful and irritating. Please Australian film, please check your work better!
