So, I just finished watching an interestingly creepy movie. Bug was directed by William Friedkin, whose resume includes such wonders as Deal of the Century, The Guardian, and Rules of Engagement. (But, also Exorcist, so he's got a touch for horror films).
Unfortunately, this film was mis-portrayed in the trailers as an actual horror film about some kind of literal bug infestation. In actuality, it's an exploration of paranoid schizophrenia, and quite a good one. Plus, Harry Connick, Jr. looking especially ripped as an ex-con was an interesting choice.
