I watched this years ago and loved it, so I was surprised to see I did not own it yet. Siberian Huskies and Paul Walker - two of my favorite things! I could watch this movie over and over again.
This movie felt like an Avengers movie despite the Captain America movie title and MIA Hulk. I originally rented the movie and liked it but was hesitant on the purchase. It's definitely a movie to see, just not a movie I had to have. I probably would not have bought if it had not been on sale on Black Friday.
This Steelbook edition appears to have all the available bonus features for Divergent. Unfortunately, it does not have a Blu-Ray 3D version, but perhaps there was never one available. I recommend buying only if you've seen the movie and liked it. If you just have a huge crush on Four, that is fine, too.
With so many editions on the market, it's hard to decide which one to buy, but the Steelbook edition appears to have them all, including the Blu-Ray 3D. So, if you want all the bonus features in one place, this looks like the one to purchase.
