As the title implies about itself, this movie understands what kind of movie it is and plays to that expectation every chance it gets. Right off the bat, the movie hides nothing from us, as it starts with a flash forward to the end when the enormous spider is fighting off helicopters at the top of a skyscraper (hm, I wonder what that is a reference to), all with some sweeping slow motion and a ballad playing over it that has nothing to do with what is happening on screen. After that the fun really starts, even as the movie goes through the usual motions of meeting the characters and setting up the plot. Though it's not exactly laugh-out-loud funny, the movie keeps up a constant humorous tone throughout, even through some of the more mundane scenes. I know I had a smile on my face practically the whole time I was watching it.
The poster really says it all, people - Big Ass Spider! is exactly what you'd want; it's hilarious; it's a great time at the movies; and yes, it is even surprisingly clever. It doesn't always take the obvious plot turns when you think it will and its great cast help make the unbelievable seem believable. Big Ass Spider! is definitely one to pick up for a fun movie night.
