A Man who was Superman (2008)

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.

Both have a character with a disability. Both of these characters change and affect their surroundings in their own special way :)
