"A Dangerous Method" is Jung (Michael Fassbender) versus Freud (Viggo Mortensen) both involved with Sabina Spielrein (Keira Knightley), one as a lover and the other her mentor.

Knightly
has the more showy role and doesn't do a  good job showing the arc she
goes through starting with her demons sending her to an institution and
ending with her becoming a successful psychoanalyst, coming on too
strong in the beginning and using her chin for too much emphasis. It is
very hard to understand how she got where she did as her intellect seems
to come out of nowhere.

Fassbender and Mortensen are quite convincing as the doctors, working quietly but forcibly, each
putting their view of psychoanalysis with the former just a bit too
quietly in a scene where he should be showing some spunk.

Many
shots in the film are of Masterpiece Theatre caliber as are parts of
the music sound track, some of the latter badly placed.

Freud
is working on a 'talking cure', the title of the play this was based on
and there is a lot of talking in this  movie plus a lot over the sound
track.

"A Dangerous Mind" is interesting, understandable, with good acting but what make a better read than it does as a film.
