When a movie is made in USA (especially not for television), people are expecting a movie at the Hollywood level. That's why when that movie can not be at this level, it will be considered worthless.
This would happened for the movie "Adventures in spying" too. If you pay attention to acting or directing and then you compare this with famous Hollywood movies, of course you will be disappointed. This is only an average fun adventure and nothing more. Maybe you can find some plot holes too, but this movie is supposed to be not serious and that's the reason for saying that any plot holes are not important.
Adventure genre films in Hollywood are mix up with other geners like action, epic, comedy, drama and also fantasy, and for that reason the real nature of the adventure genre is forgotten.
This movie does not very well succeed in portraying the adventure genre, but the mood of this genre can be seen there, even though in incomplete ways but at least it's close to that.
As I mentioned above, if this movie were made in another country, probably it wouldn't be ignored as it now is.
