Our list kicks off with the least-bad and certainly most watchable TV show on this list, SyFy's Krypton. It's always smart to keep your expectations low when it comes to SyFy shows, and this Superman prequel, set 200 years before the Man of Steel's birth, is certainly no exception.
There are sparse moments of success - Brainiac (Blake Ritson) gets his most agreeably hideous live-action showing to date - though the series is too often waylaid by mind-numbing expository dialogue, and often mistakes its convoluted plotting for smart complexity.
The visual effects and production design are generally far better than you'd reasonably expect for a SyFy show, and limiting the season to just ten episodes was a smart choice, but you'll need a serious tolerance for creaky writing and narrative bloat to make it all the way to the end.
Despite the evidently high cost of production and mixed reviews from critics, a second season has already been confirmed for next year. There's definitely room for the show to find its footing in season two, though this was a decidedly and predictably middling start for such an intriguing premise.
