Dispite it's many 'annoying' moments
I said "annoying" because the writer has created an almost unrealistic world to make the worst possibly go wrong for anyone jumping into a relationship that ends up taking a wrong turn somewhere.
If you can look past this, you will find this movie hilarious.
However, if you can't you will be saying something to the effect of:
"COME ON!"
"PUH LEEZE"
or
"YEAH RIGHT"
through out 60% of it. Unless you are a girl... then you might be saying something quite the opposite.
