Eggsy is a street kid who's father had been training to become an operative with the Kingsmen when he was killed. Eggsy grew up to become an honest but mischievous thief. His mother is now living with an abusive man who beats her and doesn't care for his stepson, and Eggsy feels the responsibility for keeping his mother and his little sister safe, even though he doesn't really know how to take care of himself. After a few problems with a stepbrother he lands himself a night in jail. He pulls in a favor and meets Harry Hart once again.
Harry Hart is a member of the Kingsman and he is the one who went to inform young Eggsy and his mother about the death of his father. After one of their members is brutally murdered, Hart and the other members bring their recruits to train to take the place of their fallen comrade. Eggsy does well but his sense of justice ends up getting the best of him.
Samuel L. Jackson plays the wonderfully delightful villain, Valentine, a man on a mission for domination and power. His ideas are of course insane, but after listening to him they actually make some amount of sense. Valentine hates blood, loves violence, but only when other people do it, and can't wait for his project to begin.
This movie was fun, full of action, and really quite delightful. I was expecting a James Bond type of tough-in-cheek action movie, and I got much more than that. The characters were all pretty well developed and there were parts of the movie that were incredibly humorous. The dialogue was fun and the banter was entertaining. There were many unexpected moments in the movie and it was just fun to watch. I seriously recommend this movie for anyone looking for something good to watch (and it's not even a horror movie).
