there be bad movie . slipstream happen to be a real bad one . the idea itself be cool . but that it . really . bad script . bat act . stupid character . plot hole . come on and the bank robber in the bus start to sing . i just do not believe this be real . i feel i have just lose another 80 minute precious time . the explanation and which character can travel back in time and and what will remain the same ( clothes and money and but not the bullet ) be a joke . probably the best part be and when the time travel ipod like gadget get hook on via usb to a laptop and because it screen break . you can probably think and that this movie be a spoof of it own . avoid this one . go and watch the butterfly effect .
