The movie was emotionally moving with great comedy. The characters despite their age showed a complex showcase of emotions and this kept me going back to the film asking for more. The soundtrack staring Flo Rida's My House is also great while we see the protagonist , potrayed excellently is a delight to hear and is visually pleasing.
The antagonists don't disappoint in their methods either.
I would say that even though you may have read the book , you should still watch this to appreciate how some stories are greatly potrayed and appreciated by the Hollywood community.
