Refined but brutal, civilized but merciless

Thus far this (the 3rd) is the most criticized of the Kingsman movie series, but I found the adventure set in WWI actually quite damn entertaining. It's packed full of action and amazingly executed bits. Lots of cool people - Ralph Fiennes, Gemma Arterton, Rhys Ifans, Djimon Hounsou, Matthew Goode, Charles Dance - in the roster.
