I'd written a review of this season of "Krypton" at about the half way point in the series. It talked, at length about how dull the series was, about how the world felt shallow and unrealistic and how I didn't care or like any of the characters. I'm subsequently glad that I didn't post that, because whilst not ever really making it to the top echelon of current TV, the second half of the series is a lot better than the first.
The story revolves around Kal-El's grandfather Seg- El (played with charm but no weight by Cameron Cuffe) as he interacts with the various councils and religious groups of Kandor. His grandfather, played by Ian McElhinery, is executed for his belief that Krypton is not alone in the universe, flying against the teachings of the gods. Several years later, his grandson is approached by Adam Strange (Shaun Sipos) who tells him that not only are they not alone, but Brainiac is on his way to accelerate the destruction of the planet.
The show picks up with the arrival of General Zod (Colin Salmon), who alongside Brainiac's possession of the Voice of Ra (Blake Ritson) escalates the plot of the final few episodes as the war for the right to defend Kandor, and then the defence itself dominate the plot - replacing the dull politicking of the first half. They, along with the present threat of "Doomsday" finally make the show interesting. There's plenty of plot available for the second series and if some of the younger, less interesting characters weren't to return, then that would be fine.
If you can persevere through the first few episodes then there are some joys to be had .
