Visual style (like Poppyland), Action, a few characters+performances (Eggsy/Merlin/Whiskey), and the soundtrack were good. The villain was ok.
The rest is ****. Script, plot, dialogue, pacing, subplots, overly long. A 5/10. What a disappointment.
Also, I think it would have been far better if they didn't write in the destruction of the Kingsman in the 2nd movie. After watching this, I thought about how I would have made the 2nd one, it doesn't involve the Golden Circle or Poppy.
I would have just made the 2nd one to be the Kingsman and the Statesman against the President, that is involved with a terrorist organization, using it as a cover for his political assassinations, to do his/her bidding. Maybe have the blue rash have something to do with this plot, too, to end the war on drugs and blame it on other organizations. I got the idea from the useless President subplot in this one, obviously.
I don't want a 3rd Kingsman movie. It's ok if you do, though. More power to you if you liked it, whoever is reading this. I really wish I could say the same, but I just despise this movie. 50% of it is entertaining, so atleast it's not a complete waste.
