in my opinion, Kingsman, the Golden circle, was very disappointing.
It has none of the charm, none of the creativity of the original. Instead, the opening scenes are a collection of special effects gimmicks which unlike in the original, go too far, and take away from the movie rather than adding to it.
That is not to say that the movie doesn't have good characters, and good parts to it, because it does. But this movie went too far and followed an all too familiar plot, by killing off two important peripheral characters; Merlin and Lancelot.
