Who is who and what is happening?

Rating: 9/10 (15 May 1999)

A guy that doesn't know who he really is: a recurrent theme in Philip K. Dick's work (see Flow my Tears the Policeman Said or Do Androids Dream of Electric Sheep). Quaid (or Hauser or whoever he is) loses his identity during the film. Is he living the memory implant he paid for, or is there a real conspiracy going on? Is he a construction worker or a secret agent? That is for the audience to decide, and, in the end, it really doesn't matter.
The film is confusing and difficult to follow, and that is exactly what makes it wonderful, different from the pre-chewed plots we're forced to swallow everyday. Beware! A good amount of thinking is demanded to follow this one.
