I liked the start of the film with its minimal dialogue good soundtrack and very effective scene setting, There is a definite gritty realism to this without ridiculous stunts or over the top car chases. As others have pointed out the main character seems to be so lacking in genuine emotion and reactions that you wonder what psychiatric problems he may have, but if this is how he is intended to be portrayed then it makes for a very different kind of character (although perhaps not a particularly sympathetic one). The film does contain some very gory violence that seemed unnecessary to me. The villains are quirkily nasty and are very effectively portrayed as low-level crooks in out of their depth. There are other great performances from the nighbouring family, Irene, her husband and son and the film builds to an exciting and violent finish.
