Which might sum up “The Love Guru” in its entirety but only at the risk of grievously understating the movie’s awfulness. A whole new vocabulary seems to be required. To say that the movie is not funny is merely to affirm the obvious. ... No, “The Love Guru” is downright antifunny, an experience that makes you wonder if you will ever laugh again.
And this is, come to think of it, something of an achievement. What is the opposite of a belly laugh? An interesting question, in a way, and to hear lines like “I think I just made a happy wee-wee” or “I’m making diarrhea noises in my cup” or to watch apprentice gurus attack one another with urine-soaked mops is to grasp the answer. --The New York Times
I think Mike Myers' first Austin Powers is inspired silliness. It makes me laugh, and yes, I have the DVD. But the second AP was so unfunny I didn't even see the third.
BONUS SLAM UPDATE: From Slate's review:
There are good movies. There are bad movies. There are movies so bad they're good (though, strangely, not the reverse). And once in a while there is a movie so bad that it takes you to a place beyond good and evil and abandons you there, shivering and alone.
Boy, they're really sharpening their knives for this one.
