Underrated horror gem
I had the privilege of catching this movie over the weekend and must say it deserves much more than a 5.9/10. I love the fact we never get an origin story (as the title suggests) of the rat. No cheesy mad scientists engaging in genetic manipulation, nor does the rat take a dip in any toxic waste dumps. The creature just appears in this poor SOB's apartment like any other vermin and starts to make his life a living hell. I also dug the not-so-subtle reference to Moby Dick and the proverbial corporate "rat race." Nice little horror flick for a rainy night.
