M.I. High is currently streaming in Australia on Amazon Prime Video, and in the US on Amazon Prime Video, and its case-by-case structure never gets in the way of the bigger story. 7 seasons is a serious commitment, but one that pays off episode after episode. With 20 viewer ratings on TMDB, this is not a title flying under the radar. Chris Stanton leads a cast that carries the story without ever feeling mechanical. There is no real reason to keep putting it off — it is right there on Amazon Prime Video.

M.I. High arrived without much fanfare and built its audience the hard way — through word of mouth. At its heart, M.I. High understands what makes crime drama work — character first, plot second. A team of undercover teenage spies working for the fictional British secret intelligence agency MI9 who have to balance their school life with their jobs as secret agents. The writing gets a boost from Chris Stanton and Jonny Freeman, who sell every scene they're in. Across 7 seasons (2007–2014), it never lost the thread that made it worth starting. What makes M.I. High hold up is that the resolution matters less than how the characters get there. It delivers reliably on what it promises, which is more than most of its competition manages.

Viewers who think they have seen every crime drama tend to find M.I. High proves them wrong. The tonal similarities to Mannix are real, though M.I. High carves out its own identity quickly. The 7-season run rewards the patience it asks of you. Watch Chris Stanton work — it is a masterclass in the genre. Few crime dramas earn their twists this consistently.

M.I. High wrapped up in 2014, created by Keith Brumpton — and 7 seasons are available to watch from start to finish.
