“Synapse” (**1/2 out of four) was an intermittently compelling and engaging futuristic melodrama in which dealers sell memories to people on the street who become addicted to them like drugs; one such dealer (Adam G. Simon) becomes chased by federal narcotics agents and various criminal underworld figures determined to keep some of these memories (and his own memories) locked and hidden forever. Half standard underworld chase thriller but also half original with a clever premise and at least it never stops moving. Very similar story was told in 1995’s excellent and underrated “Strange Days.”ynapse” (**1/2 out of four) was an intermittently compelling and engaging futuristic melodrama in which dealers sell memories to people on the street who become addicted to them like drugs; one such dealer (Adam G.
