It's unfortunate to see this from people that don't see their own hypocrisy and situation.
Mungiu tells us throughout the film that Romanians are not the kind of people that are very well defined. Yeah, we speak a language that survived russian, otoman and hungarian influence time and time again but our culture is a mix of all three, all three of these empires left a mark, in a way or another - we do have some rougue words from all three. The important thing we need to look after is that there are characters that speak 3 languages here. It's not for nothing.
Even so, Mungiu also tells us that we are part of this Earth, together, it doesn't matter where we come from, we can be anywhere in the world within 24 hours. Of course, the racism discourse is strong in romanians - originally towards the gypsies - but later we have been heavily influenced in this regard by the Western discourse regarding foreigners. These are not original thoughts, just recycled ideas from our western friends. Fortunately, I live in a city that is more open minded and we don't have this kind of issues here.
This entire film is also influenced by other important cinemas, just like any literate filmmaker will do. Another layer of the film. The "In the Mood for Love" theme is not there because of romance only. The film is filmed well, the sound is great, it's universal in its theme, we can hear like 6 languages spoken throughout, and dramatically is very effective and strong.
