In an era where just about every streaming service continuously ups their prices every few months, it’s nice to have Tubi, a streamer that still remains free. Sure, you’ve got to put up with commercials, but that’s the price you pay when you don’t have a price to pay. Every month, Tubi adds tons of new titles to its library in just about every genre, including science fiction. For example, just this month it added several solid sci-fi classics, a couple of which were even directed by the great Steven Spielberg — perfect for reacquainting yourself with the director ahead of his return to sci-fi later this year.
