I just wrote a 'Controversy' section on the [s:16plk2sc]Alton Towers[/s:16plk2sc] Thorpe Park Wikipedia page, including the Vortex/Watchdog scandal, the Saw break down and of course the suggestive stickers and video (with reference links to the clip).
ElectricBill, there's a few faults with your controversy section on Thorpe.
In 2001, the BBC Controversy programme 'Watchdog' featured Thorpe Park for falsly advertising the new Vortex ride as open when it was yet to be built. A short investigation was carried out until Thorpe Park opened the ride later that year.
When it was announced that Thorpe Park's new 2009 roller coaster would be themed with the Saw film franchise, it was questioned whether horror and gore was an appropriate theme for a popular attraction.
Both of those need a source. I never heard anyone say it wasn't an appropriate theme, or is that just what you think?
After Saw: The Ride opened for the first time to a selection of special guest celebrities, the ride malfunctioned and broke down, leaving several stranded on the ride  On the weekend that the ride opened to the public, it was only open for an hour and a half on the Saturday morning before breaking down and remaining closed for the rest of the weekend.
That's not a controversy, that's just a ride breaking down. If it injured someone due to poor maintenance by Thorpe, then it would be.
In 2009, Thorpe Park gained sponsorship from the chocolate bar Snickers. In the area around Stealth, posters reading "Are you man enough?" were put up, as well as stickers placed on the inside of the ride's seats saying "Bricking it?" and "What's hard, fast and up in seconds?". Many people have shown their annoyance towards the stickers asking if suggestive jokes are actually suitable for a theme park with young children present.
Again, who have "shown their annoyance", or is it just your personal opinion? Overall though a good idea, but no Thorpe controversy section is complete without a section saying how often their rides are shut down! :)
Back on topic: I have the feeling we may be seeing this come up in one of the tabloid rags very soon... ;)
