The E! Moron Genre
Cool as Ice, Simon Sez (Rodman), and The Hottie and the Nottie (Hilton) are stellar examples what I'd call the E! Moron Genre. These are films made by talentless morons who became stars courtesy of their ability to mug for the celebrity media and tabloids. They tend to be rated 2.5 stars or less. They also usually come at the end of their 15 minutes of fame (or maybe they put it out of its misery lol!).
Any others you'd add to this list? Sadly, I'm afraid it's only a matter of time before the Kardashians cough up some hairball.
