I was bored.

I'd like to believe that Deranged is a poor misinterpretation of the title. If it is not, then this movie is poorly named. Frenzied is probably more appropriate. Basically, a man is trying to save his family from a pandemic. His ex-colleague is trying to cure it, while is brother, a cop, is trying to get down to the bottom of the misshapen corpses being found in waterways.

The premise is sound. The execution was not. There are plot holes that can't be ignored. The writing was slow. I think some crucial scenes remained on the cutting room floor. The acting was good enough. It wasn't great nor was it poor. It just was. The music conveyed the emotion of the scenes so it was good.

Overall, I would not recommend this movie. There's no way I would have fallen asleep late morning on a thriller unless it was much less than thrilling.
