“Kingsman: The Secret Service,” an action adventure thrill ride from “X-Men: First Class” director Matthew Vaughn, gives viewers Colin Firth as he’s never been seen before — a fighter, not a lover.

By far the most mainstream work in the long and celebrated filmography of the Academy Award-winner, Firth is charming and dynamic in this modern imagining of independent gentleman spies and everything you could possibly hope for out of an international man of mystery.

Homage to spy films throughout the decades, “Kingsman” has a lot of the uninhibited panache of a Roger Moore-era James Bond film with the violence turned up to 11.

Parents of younger viewers need to be aware that “Kingsman” cranks up the gore considerably, especially during the chaotic fight sequence in the church featured in the trailer, which could be considered a ‘G’ or ‘PG’ rate cut in comparison to the hard ‘R’ version shown in theaters.

Though talented actors — Samuel L. Jackson, Mark Strong, Michael Caine — are littered throughout the supporting cast, Firth is worth the price of admission and the only real reason to see “Kingsman.”

Don’t try and understand all the nuances of an uneven film, but sit back, relax and enjoy vintage spy comedy in a modern age.
