Thankfully, they are not too spoiler-ish, as you will be having a lot to look forward to with this series.
I'll also add that it's not your typical "SYFY" or CW DC show. Just take a look at Brainiac below! It's better than a lot of movies.
I highly recommend Krypton and suggest you give the series a chance.
Episode 101 – Pilot (March 21)

Krypton premiers Wednesday, March 21st at 10/9C.
What if Superman never existed? Set two generations before the destruction of Superman’s home planet, KRYPTON follows Seg-El (Cameron Cuffe), the legendary Man of Steel’s grandfather, as a young man who is faced with a life and death conflict – save his home planet or let it be destroyed in order to restore the fate of his future grandson. With Krypton’s leadership in disarray and the House of El ostracized, Seg finds himself in a difficult position. He must redeem his family’s honor and protect the ones he loves while being challenged by familiar DC characters Brainiac (Blake Ritson) and Earthly time-traveler Adam Strange (Shaun Sipos).
Krypton is from Warner Horizon Scripted Television and is executive produced by David S. Goyer (“Man of Steel,” “Batman v Superman: Dawn of Justice,” “The Dark Knight Trilogy”) through his Phantom Four banner, alongside Cameron Welsh, who serves as showrunner. In addition to Cuffe, Sipos and Ritson, the show also stars Georgina Campbell (“Broadchurch”), Elliot Cowan (“Da Vinci’s Demons”), Ann Ogbomo (“World War Z”), Rasmus Hardiker (“Your Highness”), Wallis Day (“Will”), Aaron Pierre (“Tennison”) and Ian McElhinney (“Game of Thrones”). Based on the DC characters created by Jerry Siegel and Joe Shuster.
