I bought the blu-ray/DVD combo pack, and it was worth every penny. The visual quality of the blu-rays looks great on my HDTV through my PS3. Everything looks very crisp, the colors look vibrant and cool when they're supposed to. Everything you'd expect in a high quality blu-ray. The audio is excellent, too. Jim Caviezel was kind of hard to hear sometimes when I was watching the program on air since he speaks in a low voice a lot, but the audio is clearer on the blu-ray, imo. I have not experienced any hiccups or artifacting anywhere, so rest assured that you'll be getting great playback.
This may seem silly, but the menus are very intuitive and easy to navigate. I love how while I'm watching an episode, I can press the UP button on my PS3 controller to pull up the menus, see which episode I'm on, etc. all while being non-intrusive on the episode. I haven't tried this on a regular blu-ray, but it works well if you are playing your disc through a PS3. The menus are also broken down into tiers, so submenus pop up as a line right above the main menus, which I prefer instead of clicking a menu and going to a whole other screen.
The show doesn't have a ton of extras on these discs, but at least there are some. There are some commentary extras and such. Not too many behind the scenes. I think there is an extended pilot, which I have yet to watch, but all in all, I'm happy with what they put on the discs. If you were looking forward to a ton of extras content, then you may be disappointed in this department, but I found it to be satisfactory.
The packaging is pretty nice. It comes in a well constructed slip cover, and then all the discs are housed in a booklet format. Blu-rays, then the DVD discs. There is also a paper for anyone who wants UltraViolet copies (I personally hate UV from prior experiences, but that's just me). It's hard to explain, but I'm sure most people have had packaging where the discs are difficult to get out. When you push down on the middle section to release the disc, and sometimes there isn't a good place to grip the edge of the disc or the mid-section just won't let go--this is not the case with this package. All the discs are secure, while also being easy to take out for quick disc swapping. It just goes to show that whoever made the packaging put some thought and care into it, and that this is a quality product.
Lastly, I typically focus on the product itself since people buying a season/film already know all about it, but I just wanted to write a brief blurb about my opinions on the show. I watched this series from day one because I am a huge fan of the Nolan brothers' work (Jonathan is the brother of Christopher Nolan who co-wrote and directed the recent Batman trilogy, Inception, The Prestige). If you enjoy their films, then it is extremely likely that you will enjoy this show. The protagonist, John Reese, is an ex-military agent who specialized in counter-terrorist hit jobs, living off the radar. He is a mysterious and dark anti-hero, much in the vein of Batman. His partner, Harold Finch, is a reclusive billionaire and computer genius who built a machine for the government to basically spy on the entire country through 24/7 wiretaps, surveillance camera footage, etc. It is built to detect and prevent acts of terror, but it ignores other premeditated acts of crime. Finch finds John and they become partners in trying to stop violent crimes. Early on, John recruits a dirty cop, Fusco, who, as the show progresses, reveals himself to be a respectable man who actually cares about helping people. Another detective, Carter, chases "the man in a suit," what the police say when referring to John. Carter is a straight cop who does not put up with corruption, or vigilantism.
All of these characters, along with many minor and recurring characters build a suspenseful, character-rich, and intricate storyline with multiple sub-plots. In my summary, it becomes pretty clear that there are many connections between this show and the Batman trilogy, so if you want a complex crime drama (I'd say this show is most closely akin to The Dark Knight), then this show will surely not disappoint. The acting is superb, too, with a great cast. Many of the actors are immediately recognizable (Jim Caviezel, Michael Emerson, Michael Kelly) and all the rest play their parts very well. It's an intelligently written and directed series that will always have you wanting more, as each episode ends with a question, cliff-hanger, or a satisfying character engagement that leaves the audience wanting to explore their world even more.
Basically: I highly recommend this series, and this blu-ray copy of it. Both top notch!!
