There are two types of spy stories: the totally unrealistic, fast moving, glamourised "à la" James Bond and the slower, more realistic ones. This film belongs to the second category, while main character Dominka, perhaps would fit better in the first, being a big, attractive, young blonde.

Obviously, your appreciation of this movie depends on your preferred style. A large part of the audience would definitely prefer the cheap thrills of a violent, fast and furious travelogue with an invincible hero bedding everybody (we live in equal opportunities times, very soon even Bond will be bisexual 😉)

I prefer the second type, even if I find slightly boring most movies based on Le Carré novels. But we're not in "Tinker, tailor" territory because Lawrence is too young and beautiful to disappear in the background like a good spy should (except the "Sparrows" of course).

Spies should not attract too much attention for obvious reasons. In this case there is a reasonable compromise between the too flashy appearance of the lead character and the miserable, dreary and dangerous daily life of spies. Expect also a considerable degree of gore, because of a torture instrument I'd never seen before and hope never to see again.
