It’s a fairly light week for new TV-on-DVD releases, but there are still some great titles hitting the shelves today! Three of this week’s highlights include:

• The first season of Syfy’s new thriller Helix (Blu-ray and DVD)
• The first season of the dark British comedy A Young Doctor’s Notebook (DVD), starring Daniel Radcliffe and Jon Hamm as the titular doctor at different stages of his life
• Animated series The Legend of Korra: Book 2 – Spirits (Blu-ray and DVD)
