Having grown up in Singapore this movie was set in Singapore and there was less 1% authentic Singapore things in it. In fact I struggled to see anything Singapore about it. The Asians were Chinese not Singaporean. It's very different. Singapore is multicultural and 90% of people live in high rise flats. Not a single was shown.
Yes there are some very rich people there but they don't talk with thick British American or some bizzare Anglo Asian accent. Found it incredibly boring but it's not my kind of movie to begin with and I'm Asian
