This movie was like a hybrid of recycled Matrix plots and an old James Bond movie (Dream sequence Level 3). Keanu Reeves could have been the star of this movie instead of LD!
Without all the CGI the movie would be nothing exceptional. This movie typifies the current genre of special effects taking over as the driving force of the movie rather than the actors and plot.
Dream sequence Level 4 seemed to be the darkest depths of the movie.
The IMAX version of the movie can blow you away with the sound and visual effects. You might want to wear ear plugs!
It all boils down to what do people really like nowadays about movies.....Is it the plot and actors or special effects?
Some of the people as they left the movie felt it was too deep to understand. I didn't have a problem with the four level dream concept with each level above affecting the lower dream levels. Also, what did the architect's really do to construct the environment of the dreamscapes? How did they do it? The plot doesn't really explain that.
But of course it just a movie about what's inside somebody's head which questions the boundaries of reality.
If anybody reads this and understands what I'm saying please spin a top to confirm I'm not dreaming!
