There is another one that is floating around: https://www.youtube.com/watch?v=ebmajdLYtT8 ( this has English subtitles so those who do not understand spoken Tamil can watch it too). it is a social commentary and value judgement about Tamil speaking people mixing a lot of English words even while speaking to other Tamilians.
There is a lot to discuss/debate about the contents of this short film. It can make many of us defensive, so watch out

(BTW, as a sidebar, one thing that distracts me is the blatant pronunciation of 'zha' as 'L' in these films. It is strange to see that in a film about speaking Tamil properly. I wonder if that has become an accepted way of saying those words with 'zha' in them.)
