Movie is based on the book written by j.k. rollings . movie was really good but it gets a bit boring in between . movie continues from where it was left in the previous movie as dumbledor told harry to finish all the hookruks and kill tom riddle but in between some difficulties come and go but three of them stay together. cast performance gets better with every movie.soundtrack was good but cinematography was awesome . overall it was a must watch movie for all the harry potter series lovers.
