5/5 Season 7 is as good as it gets
  by Bww
Just finished watching Season 7 (purchased from Amazon UK) and it was so good, every minute was packed with so much tension you really cannot turn away.

If you cannot wait for the US release purchase a region free player (search on Amazon for one, I use the Philips that cost ~50.00 and it great) and get this dvd, yu will not regret it.

5/5 Great series
  by Tim D. Sawyer (FT. Worth, TX USA)
I have enjoyed all 7 seasons of MI-5 on DVD of which I purchased each season separately except for this season of which I got from [...]. This special set contains seasons 1-7 and I only paid $105.00 with free shipping and the quality of the dvd's are excellent with full menu's and crystal clear sound and widescreen picture as in the regular dvd's sold stateside. I would highly recommend buying this full season 1-7 set than shelling out 40.00 or more for each season separately. I originally bought the set as a gift and to see if the dvd's were the quality as advertised, they are.

4/5 Spooks and Spies...the British edition!
  by Shopper (USA)
MI-5 (or Spooks, its original title) is a long running, award winning British spy series that has enjoyed continued success in Britain and abroad. In the US however, A&E, PBS and BBCA have tried broadcasting the series (seasons 1-4) to universally disappointing ratings. It is no wander though: in order to accommodate commercials, each original episode was mercilessly cut down by a quarter of its running time (from 59 min to 45 min !!!), making it virtually incomprehensible. Thankfully, we have DVD's and can enjoy the series as it was intended! ;o)

Another good news is that Season 7 is the best yet and can be easily followed even without the benefit of the prior six seasons. In episode one we are introduced to a new character, Lucas North, a senior case officer released in a Russian-British spy exchange after eight years in a Russian prison. His story arcs thru entire season 7, though most episodes are self enclosed and deal with subplots relevant to today's viewer. We have nuclear attacks, bank collapse, and the thread of internal espionage (after eight years in Russia, to whom is Lucas really loyal?).

In addition to excellent writing, the series offers inspired casting in lead, supporting and visiting star roles. Mathew Macfayden (Pride and Prejudice), Rupert Penry Jones (Persuasion), Gemma Jones (Bridget Jones Diary), Hugh Laurie (House), Anthony Head (Buffy the Vampire Slayer) are only a few examples. In season 7, the handsome Richard Armitage (Robin Hood, North and South) is Lucas North. It is this actor's charisma as well as the return to Russians as the true and tried "bad guys" that brings new interest to the series.

Interestingly, even though the release date in the US is still uncertain, the set has been available in Australia (Region 4) since April, and will be released in the UK (Region 2) in October. If you want instant gratification (don't we all?), all you need is a region free DVD player.

Enjoy!

BTW: MI-5 is the British Security Service, the equivalent of FBI in the US, I suppose.
