M 15+ doesnt mean its more than a children program.. it means.. it is not suitable for children under 15 without parents.. because there can be scenes, themes, language or even violence which a children under 15 wont be able to understand and may have impact on their mind...

adults do watch harry potter... i read and watched every single of them.. and they day movies got released.. there were seniors in the movies...

its all about taste nothing more...

i dont watch horror movies.. not because i am afraid of ghost or things like tht.. i dont like those kind of movies.. i dont see any plot...
science fiction movie o tai bola jaay.. but atleast i can understand the theme
