This is definitely a more artsy season than the others, but after last season's ending it was almost necessary to slow things down for the first few episodes and amp up the nightmare images and dreamscapes. But after some reflection, things take some crazy turns and it's ridiculously entertaining. There's pretty much two seasons of events here, and basically two season finales. I'm assuming the Red Dragon plot line was moved up because of cancellation fears. Unfortunately, those fears were realized, but I'm still holding out hope for someone to pick it back up when the contract with Amazon Instant Video expires. The last episode can definitely be viewed as a series finale if that doesn't happen, though, and is pretty satisfying.
There's a ton of extras on the BluRay and DVD. Almost every episode has a version with commentary, there's some deleted scenes (even an alternate after credits scene), some pretty hilarious bloopers, a few making-of documentaries, and some interviews. There's even a whole special dedicated to the "Fannibals" or the fans of the show which shows off cosplay and art and another special talking about the nature of the relationship between Hannibal Lecter and Will Graham (and some more takes a bunch of fans asked for from that ending).
Overall, this is a great season to have on disk that was released with a lot of great extras. Highly recommended.
