Haunters (2010)

Despite the fact that Haunters is a movie and Aftermath a web-drama (with a second season), if you liked one you'd probably like the other too. Both feature the fight between two people with similar mysterious supernatural powers fighting each other.

This may not appear similar, but you would definitely like Haunters (2010) if you enjoy A Man Who Was Superman (2008)
Similarities
-A humble average human finds himself called to save, and help other people
-The world is cruel and unkind in both stories
-Both are superhero stories, but not told in the conventional Marvel/DC way
-There is more of a realist perspective in both stories/the fantastical element is limited in both stories
-Both surprisingly are heartfelt with the moral of always helping others

Differences
- (Spoiler) The main leads DOES have superpowers in Haunters (2010), whereas, the main lead believes he is superman in A Man Who Was Superman (2008), in reality, he is just a regular man
-There is a villain in Haunters (2010), and he is a menace. There is technically no villain in A Man Who Was Superman (2008)
-The female lead is a cynic producer in A Man Who Was Superman (2008) while the female lead in Haunters (2010) is a sweet, average girl
-Haunters (2010) is darker than A Man Who Was Superman (2008) while A Man Who Was Superman (2008) will just make you cry
In my opinion, this could easily be a double-feature for both films interesting take of the superhero genre. I WISH there were more "superhero" stories like both these films... Ah well.

this is the japanese version of haunters. the storyis the same but if u do like haunters, you probably gonna like this movie too

Action and psychological with super enhance humans. Of course, an epic battle scenes ensures.
