I want to start with my favorite film "1+1" of 2011.
The story being told is actually not so much a drama as a story, somewhat life-affirming. The friendship of two people from completely different social backgrounds, so different that they can be considered literally different worlds. The friendship of people who at other times could not meet anywhere, but tragedy brought them together.

"1+1" is an enjoyable film, well shot, well written and talentedly acted. The main screen duo, Francois Cluzet and Omar Sy, harmonize very well together, even if at first their images look as contrasting as possible. However, the chemistry between the characters is definitely felt, and the lion's share of the film's charm is built on it.
Likewise, in our acquaintances, we are all different in nationality, religion, age, but social status, but if we have chemistry, then we will be happy.
