hitman a nice moive

I have been waiting for the movie "Hitman" for a long time, and finally I watched it because I am a super fans of this game. This game is developed by a company called IO in Denmark and it has 4 series so far. I remembered when I first played this game, I couldn't admire more about the great idea of the game: you acted as a hitman who named 47 to assassinate certain people for money. In addition, I have convinced my father to play this game and he really got into it. After several years later, it has become a movie, which was wonderful news for me. However, finishing the movie, I felt a little frustrated.
Although the movie was about Hitman, the scenarist just like created a new story based on the game. I totally could not find any connection between the movie and the game. Also, the actor who acted the 47 was not what I expected. Probably the one in the game has impressed me a lot but I won't say I satisfied with the movie. The actor was a little bit young so he looks not that mature except his stony expression.Furthermore, to my surprise, the agent 47 always stayed with a woman in the movie, which has completely destroyed the image of 47 in the game.
Well, I think it does not happens occasionally because if people really love a novel or a game, after they become a movie, every single change will make people uncomfortable so I don't wanna complain anymore and what should I do is go back to the game and enjoy myself haha
