What a waste of my time!!!

Plot so thin, it passes unnoticed.

Great story, amazing characters, superb action, enthralling cinematography. Yes, this is something I am glad I spent money on.

One of the film's great tricks is that, for a time, you think it will go down a rabbit hole of unrealistic glorification.

You've seen movie like this a lot, its still formulaic, cliché and everything. But, if it still make you wanna watch it till the end, it still got you. Wonderful Nightmare just like any movie from the same genre that tell you about some bad people who got into some other medium that will change their life forever. We know what will happen in the end, whether the main character will change or not, but we still enjoy watching their transition. I love this movie, well-crafted film making, with some experienced korean actors, nice script and everything. I totally recommend this movie for all korean cinema lover. Even for anyone who want to try some korean cinema, this one can be quite a good start. Enjoy!

This plot device has been done many times before. You know, where a characters goes into a alternate dimension or to the past or the future or, take possession of another person's body or appearance and makes a difference in the people's life. And it also changes the protagonist view point during that process. Yes, it's been done so many times in movies before. This is a passable movie, but it just doesn't stand out much at all when it comes to these types of genre. It's like they copied a bunch of scenarios from other movies that deals with this similar situation and just combined few of them. It's actually quite obvious the Director copied few elements from the movie "The Adjustment Bureau" as well. Well at least emulated it. There isn't anything really all that bad about this movie. And I did like the message about family, although some may agree and some won't. Considering the marriage rate in Korea and japan right now. So yeah, it's a passable movie but it's also so so darn average to the point it's easily forgettable.6/10
