I have to say I felt that Memento was only good for a single watching. This may be an oversimplification, but if you reorganized the movie with all the scenes in reverse it would just be a mediocre movie about a guy who can't remember anything and the people he interacts with. I guess I just felt it was gimmicky. Primer, on the other hand doesn't use a single editing gimmick or plot twist, but rather does a deep drive in the mind bending situations that can occur when time travel becomes possible.
