Real life often tells great stories. The story in "scum" might be real, but it's not good, and not told well. There is no no dramatic arc, no line of development and no real ending. The story seems to live mainly from its "shock value". - And that simply isn't enough.
I also didn't find the characters realistic, nor interesting. A movie that wants to be as realistic as this one, needs a better script. It had a very documentary style - no music, no visual characteristics. Pretty much all this movie wanted, was to be realistic. It failed in that aspect.
The movie managed to shock and arouse though. The film-makers achieved that goal. The movie got a lot of attention. In this case, that's a good thing. Also, some psychological aspects and some of the conversations are quite interesting. But still, "scum" simply isn't a good movie.
