I'm surprised that you say that there was a lot of hype when it was released. I remember seeing a lot of hype before it came out, but all of the discussion I saw when it was released was just complaints about the audio mixing and lack of character development.

For the record I like the movie as an action movie. I feel like it's at a similar quality to most of his Batman movies and Inception in that sense. I just don't think it was ever intended to be profound or particularly deep (outside of the standard complexity that comes with a time travel story)
