Matthew Vaughn is so good at making fun action movies. Sure the violence and language tend to push these to being rated R but it's totally worth it. This is a movie made for teenage boys but done well enough that grown ups can appreciate the guilty pleasure that it is. Samuel L Jackson is at his over the top best. Colin Firth is surprisingly badass. The side characters are entertaining as hell. It was just a whole lot of over the top fun.
I would definitely recommend people checking this out. It was a lot of fun and almost Tarantinoesque with its witty banter and crazy violence.
