Some of these reviews are misleading in their claims that the set's status as 'Complete Series' is misleading.
The set is exactly what it says on the tin; all 22 episodes of the first and only season of Flashforward which aired on ABC in the US during the 2009/2010 television season. It tells the complete story of the first flashforward, what everyone saw, what it likely meant and the explanation (mostly) of what caused it. It also takes the last few minutes of the final episode to set up the events of a second season based on what the main characters saw/see in their second flashforward but ABC decided to pass on a second season and so we don't see what happens to some of the characters. This is a small source of frustration but hardly the fault of the show's creators.
Personally I really enjoyed watching the series on this DVD boxset because I had seen the first few episodes back in 2010 when they aired here in the UK on Channel 5 and I thought they were pretty good. Then I heard it got cancelled in the US and no longer felt the urge to make sure I didn't miss any episodes. However I then read all over the internet that the series had picked back up in momentum towards the second half of the season and was now considered one of the best shows not to get a second season (like Firefly which I also missed when it aired but ended up watching on DVD and enjoying immensely) and so for £9.99 (the then price, now £7.99 a time of writing) I figured there was nothing to lose.
This now has a prize place in the main TV section of my extensive DVD collection which is usually reserved for top shows like The Wire, Friends, The West Wing or Battlestar Galactica's first 3 seasons. It is one of only two TV shows with less than three seasons in that section rightfully earning its place right next to the other one; the aforementioned Firefly.
The series has a loosely sci-fi premise but as the storyline progresses it comes closer to science fact and the reason behind the flashforward becomes clearer. If I were to categorise this show it would fall primarily into the action/sci-fi genre but there is also an element of intellectual mystery speckled throughout. Some people say it was trying to hard to be like LOST but having watched both I would say that is not the case. The show is similar in that it shared some actors, the network and the fact that there was an overarching conspiracy or mystery to the show but where LOST ran on for years and ultimately failed to live up to expectations with its finale (though, personally, quite liked the final episode) Flashforward really had something based in science which could be explained to the viewers in what I imagine could have been a gripping series finale, maybe 4 or 5 seasons down the road.
Sadly this never got a chance to be the case but nonetheless it is a great story as it stands and is worth watching more than once.
Buy this DVD. You will not regret it.
