Plato pitted rationality against desire and passion, with the latter needing to be harnessed by the former. Pascal said that "the heart has reasons that Reason cannot know", elevating love to a higher epistemological plane than rationality. Brokeback Mountain advertised love as a "force of nature" - uncontrollable, like a hurricane, impartial with regard to who it comes upon and apathetic to the suffering it may cause. Damned if you deny it. Just as damned if you don't.
Into this ongoing story of love stepped Like Crazy, a film about transatlanticism that would never leave the two lovers alone. But rather than absence making the heart grow fonder, their repeated absences only makes them needier, less trusting and trustworthy. What began as a source of vitality degenerates into a deadly disease eating away at their souls. The love portrayed cannot be lived without and cannot be lived with. It is at once keeping alive and killing.
The film does a reasonable job of telling this canonical trope, with love not so much being care for another as it is addiction to another, the love story resembling the efforts of two junkies desperately chasing that same high that made them who they are. It doesn't hurt that one of those junkies is the beautiful Felicity Jones, who also played the love interest in Cemetery Junction. Jennifer Lawrence is in this film too - a fact definitely worth mentioning. I also like that the man's job in this film is furniture making. It's a nice reminder that it's okay for a man not to have to wear a suit to work.
I can't say I was emotionally moved by the film, however. I'm not averse to crying in front of moving pictures, but this one elicited no tears, no strong desire for how the story should end. I never quite entered the lovers' solipsistic world. How could I?
One final note: the actors apparently improvised much of the dialogue to give the film an air of realism. I wonder if it works like that? As Ian McKellen explained in Extras, acting is pretending to be something you are not. Improvising could be described as pretending not to be an actor, which amounts to a double pretence. Does that make things more real or less? I suppose the proof is in the pudding, so you'll just have to see for yourself.
