"These unseen gems are mostly still out there, lurking in the darkest & remotest corners of streaming services, or as DVDs on some shelf somewhere. Ever since George Méliès released 'Le Voyage dans la Lune' ('A Trip to the Moon') back in 1902, there has been a strong demand for speculative fiction at movie theaters. From 'Frankenstein' & 'Metropolis' to modern multimillion dollar blockbusters, it's a forward-looking (yet rarely optimistic) genre that's changed over time to match the technology & events of the day. However, as that technology improves, more & more sci-fi films get made — these days, it's easier than ever for a film to slip under the radar. Here, then, is a selection of science fiction movies that never quite got the audience they deserved, and that have gone on to be unfairly forgotten. Some have aged better than others, but they're all more than worthy of your time. So, buckle up: It's time to boldly go where not quite enough people have gone before." - slashfilm.com
