I've seen it yesterday, I liked it a lot. The first one was certainly better,
IMHO a masterpiece, but the sequel is still a very good one.
Considering how the americans were portrayed in the movie maybe this sequel is not going to gross as much as the first one in the USA
But presidents are not particularly loved these days and who cares about Kentucky?
So it may be appreciated in the USA as well.
About the James Bond comparison, this is basically a parodistic comedy. It can be compared with some old bond movies, the Roger Moore ones maybe, since the latest episodes with Daniel Craig are too serious and boring. Kingsman is the new real James Bond franchise.
