Well-written and fast-paced, with lots of crackling dialogue.

Most of the fun is watching Tierney be irredeemably psychotic, but otherwise the film is utterly without nuance and serves mainly as quick & dirty entertainment. Some of the dialogue is pretty good, but a lot of it is really clunky. There's some minor plot holes and implausibilities as well. But it's fairly fun and has a real gritty edge to it. I liked the bit about using a funeral procession to make a getaway. Tierney's little brother Edward has a role, but leaves no impression.
