For me this movie is one of the best movies released in year 2011. Until now One Day is the best online movie I've seen this year. If a movie can keep me focused for the full movie time, that's really great. Anyway, Action may boast of one of the biggest numbers of good movies. What determines the phenomenon of this movie? It's realism, taking care of psychological probability?. One Day is one of the best possible choice for a saturday evening with cinema.
