A much better title would be "Monkey VS Monster". They have a chimp turn into what looks like a big stuffed toy monkey and a Gila monster that turns into some sort of large lizard. Terrible dialog, bad acting, bad CGI makes for a very funny film. Lots of "WTF's which will keep you scratching your head. Gave it a 2 instead of a 1 due to the somewhat entertainment we got out of this.
