Really enjoyed this film. Simple, tense, twisty, exceptionally acted by both leads (with a slight edge going to Frank John Hughes, who sold his character to me 100%). It's a little talky, which makes sense given its roots as a stage play, but that doesn't detract from its value thanks to the performances. I also found much of the dialogue and discussion between the two leads to be compelling and thought-provoking. Some people might also find its stage roots apparent given that it takes place largely on one set, but that shouldn't be enough to lessen the experience. It's a shame that this film, like so many solid independent films, didn't get a wider audience in the first place, especially since there's so much big-budget Hollywood drivel clogging the theaters. But I personally liked it enough to purchase the DVD.
Highly recommended to anyone who likes a good thriller, an intense character study, or just plain strong acting.
