Ca Brule is all interiority and symbolism. It's almost like a test for emotional and semiotic intelligence. In order to enjoy (or even follow) this film, you need to be able to read things on a literary/ symbolic level, and you need to read a person's face and imagine what they might be feeling (in short, empathize). People who don't have these skills will be "bored" by this film and think "nothing is happening." It is not difficult, however; the symbols it uses are very basic. The horse stands for man and sexuality or physicality; fire evokes emotion, passion, and raw feelings. The character is simple as well-- a somewhat spoiled, definitely self-absorbed girl who likes a man and has a lot of time on her hands.
Watching this film requires you to sit and think for awhile about this character and what is good or bad, advantageous or perilous about her. You need a bit of your own interior life too-- it asks you to "bring" something to the film. It is actually more engaging and rewarding when a film is like this.
