Brilliant movie! In the surface level, people's perspective would be this Sacha is trolling people but for me there's a deeper meaning to it. He tries to portray a cartoonish fictional with a sprinkle of reality character. Borat is very naive and honest (that's why I root for him) but his culture is very different. Each scene really pranks people but it's not just a regular prank like the usual TV show, it kinds of putting people on edge and it reveals day to day people's true character which I find very interesting through out the film. It gives you perspective how people think around racism, sexism, politics.
I think this movie is for adult since there's like deeper meaning behind it and there are some actions shouldn't be copied because you can get a lot of trouble and putting yourself in danger by doing that.
