Mostly good, but with a flaw that destroys most of the movie

Rating: 7/10 (26 December 2011)

To start things off, i really like movies. Lots of movies. In different genres. I like hyper violence and i like sad, artsy movies that no sane person would sit through and i like big blockbusters and everything in between as long as its good in my world and the world thats within that movie.
I understand this movie and i understand what people like in it. I like some of its elements too. I love the soundtrack and the contrasts between control and insanity and between calmness and panic. I like the graphic style and the surrounding feeling of it. I loved the scenes where he fell in love with the girl. I loved the tension and strong emotions portrayed with minimalism. But the things i don't like is so severe that it just irritates the hell out of me and i cant get it out of my head. The fact that so many didn't react or write about the things i reacted to just makes me doubt my own sanity. After i was done watching it, i went through some trouble and long hours reading up on other peoples opinions just trying to find clues of why i didn't like it and so many did.
OK, so what didn't i like?
I think the major issue i had with the movie is a major and growing problem, and that this movie just was the last drop for me personally so to speak, and it ruined it for me. I have just had it with some things in story telling in movies. One of the most annoying thing is how they portray gangsters and mafia in action/drama/gangster movies. It just seems so tiny and unorganised and weak and sloppy and braindead and totally insane that what seems like big crime syndicates can fall so easy. You only see a couple of guys and thats it. Of course there are more people behind them that the movie doesn't show (cant have the movie go on for 17 hours just to show all the bad guys) but the way its presented its totally unbelievable and unrealistic (within the realms of the particular movie's universe ofc). I understand that those big organisations don't count on a guy like this and that it could happen the way it did and that its random and bla bla bla. But its been done so many times, and in such bad ways that it makes me sick. It destroys the whole movie. OK, these guys weren't the biggest organisation in the west, but big enough. I love crazy ass movies that have a sic and twisted universe that is unreal and different from our own. But the movie always have to be believable within the universe it creates for itself. Always. Thats one of the most important things for me in a movie, and if it falls short, everything starts to fall. Eternal sunshine of the spotless mind made perfect sense to me. So did brazil and twelve monkeys. So did scarface and taxidriver and Rocky and even day after tomorrow (yes, i said it!)(just to mention a few examples). Warrior fell short a little bit, but not as much as drive.
Am i nitpicking when i hate this movie based on the way it portraits the gangsters he goes toe to toe with? I am trying really hard to forget it. To just let it slide. To let all the good things about the move win me over and relax.
But where should i draw the line then? When is it enough?
