Movie: I'll Sleep When I'm Dead

OK, what is it about modern British action dramas that are really slow on the action part? and really dreary on the drama part? I can't say this tale of a gent finding his brother's murderer is, well, er, bad exactly, but c'mon - an awful lot of time is spent mulling over awful, mundane truths. Maybe, on reflection, it is actually quite realistic & believable ... which isn't necessarily what paying audiences are looking for.
