Graham Cunningham, racing TV broadcaster in the UK and freelance writer: "5 horses killed in action in 2 days at the Cheltenham festival. It’s a hard trade off but one millions buy into in uk and ire"
He has a point…in the US 5 dead horses in 2 days on one track would be considered an utter catastrophe and would lead to the immediate suspension of racing on that track. If those deaths occurred in a major televised meet (i.e. the Breeders Cup) horse racing itself would be in serious jeopardy in this country, from fans and legislators.
In other words, I get the feeling that if Luck were a UK-based show they’d just keep on filming with little to no backlash.
I’d hope that the UK wouldn’t commission such a load of rubbish! 
I presume you have not been unfortunate enough to encounter daytime television then?
