EDIT: After seeing this a second time it is still a lot of fun with over the top action and humor. Still needs more Channing Tatum and Jeff Bridges.

First off, if you didn't like the first then this one isn't going to win you over. It is the same crazy action with some dirty humor and over the top plot. There aren't many movies that have the same stylized action scenes like Kingsman (even though there wasn't a scene like the church scene from the first). All the cast were great included the great Elton John. Not as great as the first, which I think is one of the best action movies of the last decade, but still a worthy follow up and I can't wait for the sequel.

Now for some spoilers:
[spoiler]I'm sad that they killed Roxy so quickly. If they can bring Harry back I hope they bring her back in the third. I laughed my ass off when I saw that Eggsy was dating the princess who let him do it in the asshole. By the end of the movie he married her and now is a prince, I wonder how that will play into the next. I thought Merlin's death was sad but built up very well and that led into the best scene of the movie. Julianne Moore's villain wasn't as good as Samuel L. Jackson's but I still thought she had some creepy style. Needed more statesman. We got a lot of Pedro Pascal but not enough Jeff Bridges and Channing Tatum, maybe next movie.[/spoiler]
