Absolutely nonsense but entertaining nonetheless, "Lucid Dream" takes a not very original idea (what is real, what is not, can we get into our dreams...) and decides to take a page of the action book. The result is an average movie, which repeats itself too much, but is saved, however, but good acting and a pace that doesn't slow down.
Dae-ho sees his son kidnapped in an amusement park. He thinks the culprit is someone that must have a grudge against him, because of his work as an investigative journalist. But, when more than three years pass and he is unable to find a clue about the whereabouts of his son or even if he is dead or alive, Dae-ho decides to ask for the help of a friend and try to find clues in his own dreams, in a state of lucid dreaming.
What follows makes no sense whatsoever. The basis of the plot, the lucid dreams and our hero remembering from his own, is as thin as it comes, and it never sells the idea that it could be a real possibility. However, as Dae-ho, Soo Go sells us the character and his plight. And the direction by Kim Joon-Sung is flashy enough to entertaining the viewer and make us forgive the shortcomings of the movie.
All in all, it is an entertaining time in front of the screen, but empty fun.
