watch memento, you jaw will be firmly on the floor and your mind blow by the end of the movie, even though the first scene of the movie is the ending 

while the early review of inception is great there is the question of the movie being too complex and too smart for the general cinema goer and may hurt the box office performance of this movie. if this movie do perform well in the box office it might hurt nolan chance to make another original movie with a massive budget, at least before batman 3 come out and his stock rise again.
