Watch it solely for Katherine Heigl.

Rating: 4/10 (5 November 2009)

************************ SPOILERS BELOW *************************
The movie is about four men devoted to talking sex trash using offensive language (i.e. language that would not be allowed in a court of law). One of the four is the male lead of KU and has not worked in years. While not being particularly attractive (overweight by any clinical method) and his attire would never make James Bond jealous, he can and does (near the end of the movie) make an attempt to curb his tongue, get a job and single living facility.
The female lead works for "E" and after being promoted to on camera status finds herself in a bar celebrating. Too much drink leads to a tryst, with the male lead, that impregnates her.
So here we have a beautiful, smart, successful lady having a baby with a dull, fat failure. She meets with the father and decides to keep the baby and give it a try "for the child's sake".
For clarification I did not hate this movie, but nether did I love it. I did watch it all through the final credits that showed snapshots from the movie.
Katherine Heigl is the sister I never had. OK, I had four sisters, but she is the one I never had. This was the only reason that I started and finished watching this absurd paring.
************** Caution this movie contains continuous foul language *********
Rating: 4/10 for language and cruelty to common sense.
PS – as part of the SPOILERS please note that there is nudity and two close ups during the birthing scene of the baby "crowning"
Comedy depends on surprise. I like to tell jokes and hear friends laugh. Once I met a man that was SO smart that he could always anticipate the ending. Being so smart the poor fellow never laughed at a joke. There must be various degrees of this smartness to laughter ratio as many, perhaps even most of the reviews for Knocked Up (KU) found this movie funny. The reviews that hated KU focused on the extreme use of language (mostly the fork word but with a u not an o). As pervasive as the language was my main problem with the move was the lack of timing required to make a joke funny.
The picture on the DVD cover of Seth Rogen smirking is the funniest thing in the movie!
