what be wrong with unforgettable . ( some spoiler ) ray liota be the husband of a district attorney who be kill while ray be pass out drunk on the front yard of their house ( and everyone think he do it ) . ray meet a scientist ( linda fiorentino ) who develop some kind of drug that she think allow one rat to use the brain fluid of another rat in order to live that rats memory . this project be in the early stage of experimentation and so ray decides to seduce linda so he can use her drug and patch into the memory of another victim of the person ray think kill his wife . linda do not react with any feeling of betrayal and and in fact become his little assistant so that ray can go from brain to brain and figure out who kill his wife . the rest of the story move along pretty well . of course and the detective who keep tell ray to get on with his life be tip his hand . aside from be predictable and give away the surprise end and unforgettable have some other minor flaw represent 1. brain fluid should not look like syfo carbonate mineral water . 2. if you stick a five inch needle into someone brain stem and a little blood might drip out . 3. if you take someone brain fluid and and then inject the brain fluid into your bloodstream ( intravenously ) then you might have a heart attack when the heart can not filter the brain fluid and but i do not see how injecting brain fluid into your arm be go to cause anyone to relive the memory of the person whose brain fluid be inject . 4. even if it do work and wouldn not the brain fluid have thousand of memory . why would it automatically go to the memory that ray liotta want to see . 5. why do linda continue to hang around when ray basically use her to get to her wonder drug and and he certainly never even give her a kiss or even say he like her . 6. why do the coroner fire ray because he order a rush blood test . seem like a real cheap department if that be how they do thing . 7. why do the bad cop blow up linda lab . ray could not prove anything regardless of how many memory he could re live . a good bad guy would have play it cool and claim that ray be crazy . anyhow and those be some of the thing that make this movie hard to get into . ray liotta cat scratch face and contortion act make it even more difficult . i like ray and but he always seem to be pretend he be the late john belushi and be constantly twitch his face and eyelid and or arm and hand . ray remind me of joe cocker when he be sing .
