Dia is, technically, a good movie [not awesome, just good], but this filmis not made for some philosophical lessons [as it pretends to be that kind of].
Acting, Direction and Background Music are the positive aspects of this movie. Especially Mother Character in the Movie is good signs of the story
At the middle of this film, we should start feeling that this is the movie which will teach me an important lesson. But in the last 15 minutes ... Oh, God... they just ruined their efforts in the ending part !!!
If we divide the movie in 4 equal parts, first 3 parts are good. The movie will take you on the roller coaster of emotions. You'll start trying to conclude a deep meaning from that. I started too! But at the end, I realise that they just wanted to make a film with lots of twists and turns, that's all. They didn't care if these turns make any sense or not.
So, Just Watch (is you want to enjoy some ups and downs in your emotions) that's it 2.5/5
