Definitely not take from early reviews on the gore. Anyways more reviews, pretty bold statement to says this is his best film over a flick like stardust ect
The Hollywood Reporter - Good
Playing a world-saving and somewhat world-weary superagent, Colin Firth is the epitome of suave, as lethal as he is elegant, in the spy thriller Kingsman: The Secret Service. His sad-eyed heroics ground the comic-book adaptation, while Samuel L. Jackson brings the goofball villainy, big-time, as a mad genius who concocts a ticking time bomb of a scheme. As he did in X-Men: First Class, director Matthew Vaughn strikes an energetic balance between cartoonish action and character-driven drama, though the tinge here is darker, with a story that hinges on matters of climate change, the insidiousness of technology and the class divide.
Variety - Good
For those who think James Bond has gotten a little too serious in his old age, "Kingsman: The Secret Service" brings the irreverence back to the British spy genre, offering a younger, streetwise variation on the 007 formula while gleefully pushing audiences' favorite elements - sartorial taste, killer toys and cracked-out supervillains - to hyperbolic extremes. Based on Mark Millar and Dave Gibbons' 2012 comicbook series and directed by Matthew Vaughn in much the same pop, over-the-top style as his earlier "Kick-Ass," Fox's franchise-ready one-off at first poses as a more teen-friendly option, before taking a hard turn into decidedly R-rated territory. Plenty have tried to adapt the 007 shtick to younger characters, with demonstrably dopey results. In the end, the reason it works for Vaughn is that he's making the film for adults.
The Wrap - 4/5
The fifth and, yes, best film from director Matthew Vaughn ("Layer Cake," "X-Men: First Class"), "Kingsman: The Secret Service" is a startlingly enjoyable and well-made action film leavened by humor and slicked along by style, made by, for, and about people who've seen far too many Bond films. Fleet-footed and unrepentantly British, it's a reunion of sorts behind the scenes for Vaughn and comics writer Mark Millar, but it's infinitely better than their 2010 collaboration "Kick-Ass." Credit for that goes to Vaughn's adaptation of the script alongside producer Jane Goldman, which finds cheer and cleverness in Millar's mixture of retro-style spy action with a snobs-versus-slobs twist.
The Guardian - The spirit of 007 is all over this movie, but Vaughn's script (written with frequent collaborator Jane Goldman) has a licence to poke fun. [The] overall vibe is sheer glee, as if no one involved in the production can believe they're getting away with making such a bats**t Bond. Millar's voice seems to be egging on Vaughn, whose last film, X-Men: First Class, was quite enjoyable but not nearly hardcore enough for denizens of the darker comic-book playgrounds [unlike 'Kingsman'].
Empire - It's hard to argue with a billion bucks at the box office, of course, but at the same time it's hard not to feel that the Bournification of the James Bond franchise may have robbed 007 of his sense of fun. Which is where Matthew Vaughn's Kingsman: The Secret Service comes in. It's got ingenious gadgets, suave heroes with the ability to identify a rare brand of Scotch from smell alone, megalomaniacal villains and deadly henchwomen with blades where their legs used to be. It's filthy, funny and very violent - and frankly it's the most fun 007 has been in years.
