Just finished Sphere (1998) for the first time. I've been building up my digital movie collection a year at a time and watching the ones that sound interesting. Sphere was one of those movies. Add to the premise a stacked cast and it was a fun watch. I love movies that keep you guessing the entire time. Another one I think of is Oculus. I remember being pleasantly confused while watching it, but that's about it. Gonna have to rewatch it soon. Give me some recommendations if you know of any.
