Through its highs and lows, the strength of Upload was always the relationship between Nathan (Robbie Amell) and Nora (Andy Allo), and the same is true of the final season. With only four episodes, this feels more like a feature film than an entire season, and honestly it could have just been one. Even so, this is a big comeback from Season Three, as creator Greg Daniels has crafted a genuinely beautiful finale that hits on every single emotion. He brings things back to what works and abandons the convoluted nature of the previous season to end Upload on a high.
