Secondly i thought there was very little plot.
I actually was telling my friend about this afterward and compared it to the Master, which seems to be similar in overall structure (i.e. a day in the life of two guys). Where The Master fails, though, End of Watch succeeds and the lack of plot is not distracting, at least not while watching the movie. It doesnt feel like it meanders. Rather, each scene builds on the audience's understanding of the relationship until the overarching plot line comes to a head. In many ways, the film is like a series of very brief episodes on TV: each episode is its own thing, but there is an overall, backbone plot line that must eventually be dealt with.
