If you're familiar with Stephen Laberge books on studies of lucid dreaming, you'll be disappointed in this movie. It takes some great ideas, mixes them with not so clever ones and deliberately confusing and frankly just boring plot and wraps it in overly serious Nolan style, which is undoubtedly style over substance.

It's okay, there are great actors ensemble. Some nice visuals. Not phenomenal and surely isn't any "masterpiece".
