On Amazon Prime:
The Grand Tour - it's essentially Top Gear, but because it's on a streaming service, they can be a bit more...open...what's not to love?
Jack Ryan - great spy thriller. John Krasinski (Jim from The Office USA) is fantastic.
The Widow - starts off slow, but really makes you think. Can be overly grandiose, and preachy, but it still tells a rock-solid story.
On Netflix:
The Stranger - must-watch. Loses steam over the final two episodes, but it's brilliant.
Safe - not as good as The Stranger, but still a gripping drama.
El Chema - it's very good, and will grab you instantly.
