For those who get the blu-ray, the movie looks and sounds great in HD. There are only a handful of extras, the most extensive of which is a six-part behind-the-scene feature titled Kingsman: The Secret Service Revealed. Then, there are image galleries, the theatrical trailer, and previews for other movies. So, while there are not a ton of extras, the making-of documentary is very well done.
Overall, the movie is a very good, over-the-top blend of action and comedy. The action sequences are very violent and gory but in a tongue-in-cheek way (similar to those in Kill Bill) as opposed to the gore in movies like Saw. The acting is wonderful all around. Jackson Hams it up constantly, Firth is great as a buttoned-down English gentleman, and Taron Egerton does a great job as the lead. There is not much in the way of sexual content (aside from innuendo) or nudity until the very end, which is basically a joke that closes out the movie. That said, it is definitely not something that is appropriate for young kids, if nothing else, because of the violence. So, if you are looking for a fun action movie that you put on to kill a couple of hours without having to watch every second of it to be able to follow what is going on, this is a good one.
