I've seen it. They are fantastic... but they are not British :(
On a show called [insert country]'s got talent, the least any viewer should expect is that all the acts are from the country in question, and not flown out to bolster up the viewer numbers and line their own pockets in the process.
But yes, they are fantastic. Would win Hungary's got talent in a heartbeat.
Yeah it makes them sound like rejects on their Country Got Talent, hence they got flown to the UK, because everybody knows nobody is from the UK. I feel ya on what you are saying.
