This is a great film overall. It's fun, action packed, and often funny at times. There is not a single moment where I was bored with it.
The characters are likeable. The story is interesting and compelling. The characters are likeable. I liked the protagonist Eggsy. He is believable and you actually care for him. Harry and Chester King are quite entertaining and likeable supporting characters. Valentine is quite an entertaining villain as well as his amputee Gazelle.
It's well acted. Colin Firth, Samuel L. Jackson, Mark Strong and Michael Caine portrayed their roles very respectively and made their roles entertaining and believable. Samuel L. Jackson did an awesome job as Valentine as well as Sofie Boutella as Gazelle.
Matthew Vaughn did a great job directing. It's beautifully shot. The action scenes are well done and downright intense. While it is mostly action packed, it leaves room for the story line and the action scenes are actually part of the story and have every reason to occur.
There is not a single thing about this film that I did not like.
Overall, I found Kingsman to be a pretty awesome film and I highly recommend it to action fans.
In the end, Kingsman: The Secret Service is a fun and compelling action masterpiece.
Kingsman: The Secret Service is now available on DVD and Blu-ray and Digital HD.
