Adam (2009)

Soon after moving in, Beth, a brainy, beautiful writer, encounters Adam, the handsome, but odd, fellow in the downstairs apartment. A pleasant chemistry flows, but his awkwardness is perplexing. Whether avoiding eye contact or standing by blithely while Beth drags a heavy load up steep stairs, Adam seems utterly oblivious to social convention. Then one night, Adam regales Beth with an elaborate outer-space light show. It’s a magical moment, tainted slightly by his obsessively thorough astronomical explanation. Their connection is palpable. It becomes clear that Adam's inability to decipher nonverbal signals is beyond his control. And yet Beth doesn’t balk. Their mutual interest tentatively takes root.
