Still Affleck gives a fine performance, and we probably have Hudson's best work in almost a decade, or at least since The Skeleton Key. Alba brings very little to the role, but her performance isn't necessarily bad either. It just is.
The Killer Inside Me isn't necessarily a terrible film, and it not a film to avoid by means, but it certainly isn't anything to rush out to see. Part's of it are certainly worth while, most notably the scenes towards the middle of the film.
The film is a semi remake of an old Vincent Pryce campy horror film. It is semi in that it was the same title, and a similar premise, but very few of the same plot details, and a very different feel. While the original was a campy 3D style film, this one is truly disturbing. That is not surprising being from director David Lynch best known for such films as Videodrome, Naked Lunch, Crash, and A History of Violence. He is known for violent, disturbing, brilliant, and emotionally brutal films.
The Fly is probably one of his strongest. It features a great performance by Jeff Goldblum as the scientist. He is sensitive, sad, and generally just deeply poignant. The film also features some of the best makeup ever put on screen. The film was made in the mid eighties before most computer effects were available, and all the effects are thanks to the make up. Turning a man slowly into a fly must have been difficult, and it is actually perfectly pulled off.
So in the end The Fly is a strongly constructed, and entertaining sci-fi horror film of sorts, and will be enjoyed by even people who aren't sci-fi fans. It will have the effect of staying with you for a while after seeing it, and not only for the horrific effects created by the makeup.
5/10 but only because of Cotillard.
