Personally I watch reality TV and usually have no problem with it. However I abhor this show for many of the following reasons.
The Kardashians have no decency, Kourtney Kardashian and her husband Scott have 2 young children. Yet Scott still goes, parties and gets drunk. This is not the way you should act when you have kids.
The language in this show is not the best either, they use a variety of bad, suggestive and sultry language.
Since the Kardashians are all one family, you would suggest them to respect each other. However, they bad mouth each other and do not even respect their parents.
The Kardashians have no value for money....
With all of this said, I would recommend this show if you were looking for a "laughable comedy." However I would caution you to let your children watch this if they are not teens.
