Absolutely enjoyed this.
Colin Firth was an absolute delight as usual - just hope he'll reappear somehow. Some gadget must have saved him from a shot in his face!!! Liked the way they made fun of spy-movies, but without putting them down. And Valentino was just hilariously evil. Loved the 2 references to Mycroft (the umbrella!!!, and of course Eggsy calling Merlin that).
Definitely looking forward to the sequel! 8/10
