I personally enjoyed it, in many ways better than 1 and 2 (never saw 3). In fact, 2 was my least favorite, and I find Woo's action sequences to be far too unrealistic to be enjoyable. I would agree that the second half of the movie slowed down significantly. Let me say that they all fall short in the story when compared to the original M:I series. I loved that show, the real spying, the real outfoxing the bad guys...very clever writing, even with the 60's special effects. I wish they could pattern a movie much closer to the series.
