1. Russell's anarchic comedy comes up with some doozy ideas, and some of the comedy is clever and on the mark.
2. Hang on and prepare to laugh continually.
3. [A] wonderfully mad odyssey of a movie, in which a man sets out to find his biological parents and winds up meeting more weirdos than Alice found down the rabbit hole.
4. There are conventions in this sort of story, and Russell seems to violate most of them. He allows the peculiarities of his characters to lead them away from the plot line and into perplexities of their own.
5. The perpetual motion is a deliciously hysterical rush. This offbeat, documentary-like comedy becomes geometrically funnier as it goes along.
6. Russell finds humanity and sympathy in each and every oddball that's dredged up from under the stones that his film turns up.
7. Although the film's frantic momentum occasionally lags, much to your chagrin, it's probably the result of some law of physics -- no movie could possibly be this funny every minute of its entire length.
8. This whacked-out road comedy about a young man's search for his real parents takes any number of unexpected turns, most of them bitingly funny.
9. David O. Russell has a twisted mind; I like that in a man.
10. Boasting a clever title, this is an inspired piece of lunacy about sociology versus biology, with terrific performances from Ben Stiller and his two sets of parents.

What is a brief summary of the following reviews?
Darkly funny, solidly cast, and surprisingly thoughtful, Flirting with Disaster proved David O. Russell's Spanking the Monkey was no fluke.
