Can you speak BM

For those who are not aware, Malaysia is made up of three main ethnic groups - the Malays, Chinese and the Indians (mostly Tamil) and other smaller ethnic groups. The national language of Malaysia is Bahasa Malaysia (BM), mother tongue of the Malays who form the majority of the population. 

The Chinese are made up of different Chinese dialect groups. This includes Hakka, Cantonese, Hokkien, Teochew, etc. Most of the younger generation of Malaysian Chinese can speak Mandarin too, due to the fact that most of them went to Chinese schools where Mandarin is the formal medium of education. National unity is issue of concern in the Country and also controversial because there are a lot of different views on how to go about it. 

Anyway, read an interesting piece of news on The New Sanctuary blog. The post titled "Chicken and Duck talk", discusses a new Malaysian TV series where most of the characters are ethnic Chinese but they speak BM. According to Anthraxxxx, this is a bad idea. He says,

"It’s fine if these casts are good and fluent in Bahasa Malaysia but if you read the article properly, most of them are not good in that Bahasa."

I haven't seen the series, so I can't really comment. What do you guys think? Would love to her the opinion of guys who have seen it.
