Person of Interest: Why you need to watch (or revisit) this sci-fi classic – now on DVD and streaming

Have you caught the buzz lately? Suddenly, everyone's talking about Person of Interest as if the show never left. I've been following TV drama for twenty years, and when a cult classic stirs back to life, I know it's time to dig out the box sets. Few series have tapped into the zeitgeist quite like this one is doing right now.

A series that saw the future coming

For those needing a refresher: Person of Interest follows the mysterious billionaire Harold Finch and former CIA operative John Reese. They utilise a surveillance system, "The Machine", which spits out the social security numbers of people about to be involved in serious crimes. It's a gritty, thought-provoking mix of crime drama and sci-fi that ran for five seasons until 2016. Back then, it was thrilling – today, it's frighteningly real.

Why is everyone talking about Person of Interest again?

A lot of the credit for this comeback has to go to the streaming services. Now the series has appeared on several platforms' line-ups, a whole new generation has discovered Finch and Reese's fight against the system. At the same time, the debate around artificial intelligence and privacy is hotter than ever. Suddenly, a ten-year-old series feels like the most relevant thing you can watch. There's also rumblings that certain production circles have floated the idea of a revival – just enough to get fans buzzing with excitement.

How to bag the complete series on DVD

For those of us who still appreciate physical media, owning the complete series is a genuine treasure. Here's what to look for if you want Person of Interest – The Complete Series on your shelf:

• Box Sets: Hunt down The Complete Series DVD – it includes all five seasons and often bonus material you won't get on streaming.
• Individual Seasons: If you're only missing parts, Person Of Interest - Season 1-4 and Person Of Interest - Season 5 are available new and used.
• Check the Region Code: Spot a cheap Person of Interest Season 4 (Region A/1) DVD online? Be careful – it requires a region 1 player. In the UK, you need region 2. Keep an eye out for Pre-Owned Region 2 editions in charity shops, second-hand stores, and UK online retailers. They pop up all the time.

Is a new season really happening?

The question on everyone's lips: Could Person of Interest genuinely see a renaissance? I wouldn't rule anything out. The industry is full of surprises, and the show's themes are even more explosive now than when it was made. However, the cast have moved on to various projects. Michael Emerson (Finch) is appearing in other big productions, and Jim Caviezel has pursued different roles. Still, in an era where everything from old crime procedurals to 90s dramas are being revived, I wouldn't be shocked if we got a miniseries or a film set in the same universe. For now, we can enjoy the five seasons we have – they're more than worth a rewatch.

So, whether you're a seasoned fan wanting to relive the atmosphere, or a newcomer curious what all the fuss is about: now's the time. Grab Person of Interest on DVD or streaming, and let yourself be drawn in.
