This movie makes top lists regularly. It was #4 on two lists posted here recently.
Because of this, I finally watched it. I wondered why the protagonist didn't have a notebook computer wherein he could have kept a time-stamped record. Failing that, I wondered why he didn't place the date and time on his memory notes and photos.
In fact, I wondered quite a few things. I wondered how an insurance salesman could be so bent on revenge. I wondered why actual tattoos were necessary.
The ending almost saved the picture, in my view. Before that, conflict and peril are mostly reduced to a memory thing, as opposed to other kinds of threats from people manipulating him; and this reduction seemed one-note. 58 minutes into the movie, I felt as if it were repetitious. However, the wrap-up still felt rather pat with its philosophy of illusion and suggestion that Leonard imagined Sammy. I wondered why Leonard changed clothes with the man he killed (Jimmy).
What sort of arc of belief about reality does Leonard have chronologically?
The movie didn't especially grab me emotionally.
Some of this is no doubt my own lack of intelligent viewing. The movie does make demands on one's intelligence.
Still and all, the thoroughness with which the film pursues its neo-noir theme of the thin veneer of reality as it depends upon memory, is a plus. What, after all, is time and the present?
What would you rate it? Would you place it among the top 10 or 25 of all neo-noirs or give it serious consideration for such a slot?
