Writer and director Paul Andrew Williams created a masterpiece for this overused genre. In the very comfortable well paced 88 min runtime, he gives us non-stop intensity, violence, suspense and gore, all within a minimal budget, used very wisely. I'm not a fan of flashbacks, but in this film they were needed, and executed perfectly, otherwise the differentiating-from-the-norm twist doesn't work. The cinematography and score was perfect. Casting and performances were outstanding by all. I did have trouble understanding some of the dialogue from the hardened Bri-ish accents, especially when speaking in lower volumes, but nevertheless, everything that happens along this fun ride, makes that small detail irrelevant. It's one of those films that you can easily watch at least one more time. Mad props to Williams for giving us this little gem, hopefully we'll get lucky and he gives us more. A well deserved 9/10 from me.
