This is quite the accomplishment. Is it as good as the first one? Probably not. That was a different time and most people didn't know the Borat character. But this one definitely has it's "Throw the Jew down the well" moment, as well as perhaps the single most cringeworthy dance scene since David Brent.
But SBC's co-star is the reason this succeeds. He's smart enough to know Borat can't carry the stunts - and she's incredible and as committed as he is.
