Lock, Stock and Two Smoking Barrels. 7/10.
Essentially a low/medium budget comedy/crime movie by Guy Ritchie. This is evident by the style and somewhat lack of detailed action sequences. However, the story is solid and funny and this movie has some of the best dialogues I have ever heard, reminiscent of Tarantino's flicks. I'd watch this movie several times and still not be tired listening to them.
Direction is typical Guy Ritchie. Like his later movies (Rock n Rolla, Snatch, etc) this one too flows through multiple, sometimes parallel but related plotlines.
The movie, also has some really good soundtracks to create the atmosphere.
Priyadarshan's Hera Pheri 2's plot is apparently copied from this movie. As you watch the movie, you will realize the resemblance, even the ending is the same.
