First of all i want to mention about this film that which is based on Novel, In The Hunger Games there's a competition known as "Televised Competition" in which two young people are randomly selected from each of Panem twelve Districts to engage in a combat to the death but here a sister (Katniss Everdeen) volunteer in order to  take her younger sister place in the Combat. Also i want to mention here that this film have sequel which are:

The book series is fantastic, and the characters were portrayed rather well in the films as for age recommendation i recommend it to 16+

Well to be very honest, The whole movie (is masterpiece to me) favorite to me but lets say i like the game that where star crossed lover started and peter is exhaling his emotions for Katniss, & at a point " I don't think winning is gonna help me at all because she came here with me" that is very heart touching moment in the movie.

I watched it on Television for the first time but i watched it on my laptop or smart lcd on different occasion too, & yeah it is worth of watching twice or thrice in your lifetime.
