Great job but there is a crucial missing

Rating: 7/10 (10 October 2019)

First of all, I saw it for the second time yesterday just to be sure about my thoughts and yes I was much more brutal about something in the movie but I feel a bit different now.
Excellent cinematography, great sceneography and splendid acting by Joaquin Phoenix YET I found some element missing. Let me first make it clear. I don't really know about DC world and the stories and for this case Batman. I chose to see this movie as a completely different world than Joker from DC. So here we have a man who is having psychological problems and goes crazy after what happened to him lately. Don't get me wrong. Movie is great overall but there is this problem I'll write about and it makes the movie ''not enough'' I'd say. Some people complain about how different this joker than the other joker(like its not like a comic thing) and it seems like similar compositions with ''Taxi Driver'' or ''King Of Comedy'' make some people ''oh its so same so its bad...''. However, these or other things that most people are talking about are not my point breakers at all.
So what are the problems?
The problem is lack of incidents for Joker to become Joker and plot it self. For those who don't know much about technical side of the screenwriting, your protagonist should be likeable or at least able to make the audience feel empathy for him/her. Even we feel connected to bad characters sometimes. Please note that, I am not supporting the idea of everything should be done by some strict rules in cinema like I gave the example of character building but apparently it is not so successfully done in this movie. I am getting the point. Obviously joker went through something even before the movie starts and we get to see him suffer after the movie starts. He gets beaten a couple of times, tries to be a comedian and fails and discovers that he is adopted and his favorite tv show man makes fun of him for his sickness ect. In that sense, the question here is: Did we feel for joker? The answer is maybe yes but believe me it was not enough. At least not enough to become a symbol for the city and start a riot. I mean camo'n... He kills three rich men, and police suspects someone dressed like a clown. So this triggers poor people to rebel with clown masks? I know there is an unemployment problem and they are going through an election, people are ready to explode already but it just still does not persuade me. The very first thing triggers his becoming Joker process happens in the beginning in the train. Especially the last scene where they save joker from the police car. Joker did't feel powerful enough to make lots of people save him and put him in a leader chair. No, he did not! I just pity him for what happened to him and thats all. There must be something bigger than that.
The movie doesn't give enough reason in terms of making audience feel enough for the protagonist to change so that we actually can believe he may lead something but this did not happen. Also, 8 stars is for what i said in the beginning. Everything other than that done so well that nearly makes me forget the fact that i mentioned about. I just wish the plot was a little more intense for joker.
All in all, still, it was enjoyable to watch thanks to great visual storytelling. Great job by Todd Phillips and his cinematographer Lawrence Sher. They did comedy before and i really was amazed how they pulled that drama off. I liked some details like the part where the rich people watch Modern Times and enjoy it which is really critically done. You see, film is overall great but plot could've done better for joker's change in my opinion. Also what the hell is wrong with people saying ''It was the best movie ever''. This movie is a true piece of art but for god's sake don't make it overrated.So good with some crucial missings
