I just noticed a little detail about Kingsman

Valentine says he can't stand seeing blood and towards the end of the film, the heads of a bunch of people explode making little colorful mushrooms. I always thought this was just a way for the filmmakers to mask the gore.

In a way it is, but I think Valentine's implants actually mask the blood with the colorful substance.

Sorry if this comes off as old news but it just struck me and made me see the film under a new light.
