I purchase this film at Best Buy on purpose - I simply want my collection to cohesively match, and I already had the prior two titles in the Divergent series in steelbook blu-ray release.
Regarding this title, the packaging is excellent. It meets the same level of quality as the previous steelbooks (similar to the Disney/Marvel releases), which is to say that they are some of the better steelbooks out there. The case finish is a pleasant texture and isn't too reflective, so it just looks nice.
The film has a bad rap, being the third in line, which is hardly a great place for most film series. I believe that it was a better entry than critics would lead you to believe. However, the tired dsytopian theme of not knowing which evil to pick is very prevalent, so if you have an aversion to that, you have been warned. Otherwise, it has no more significant plot holes than any other teen-becoming-adult-oriented action film, and does a fairly good job at creating an immersive, entertaining world in which to reside for roughly two hours. It won't likely capture you for much longer after that.
NOTE: My biggest complaint about this release, and the primary reason why the rating isn't at least four stars (targeted at the studios and production, rather than this product itself) is that it doesn't have a 3D option at all. Divergent didn't because it almost didn't release in theatres in 3D, so they had nothing to give us without costly conversions. Insurgent got the full treatment, and is actually a good example of some very good (not excellent) 3D material. I love that the steelbook for that one included the extra disc. Allegiant, being the latest entry, had a 3D presence in the box office that surpassed the prior film, yet it has no 3D upon home release! Reasoning? Probably just that they're too cheap to port an existing 3D video source (essentially the same as what was shown in theatres, but with very minor differences in codec handling) to one additional disc for those of us who still care about the admittedly niche market of 3D in home threatre. But the cost savings of a dollar or two for a 3D disc in a premium steelbook package is really a shame, considering that almost everything else here would have merited a higher rating. But given the cost, this is a bit of a letdown.
