I found this movie unrealistic

Even if it's intense and acting and directing good in general, I just find it unrealistic.

First of all Thailand is not a country I would expect something like this. I don't think Thailand is a dangerous country at all and picturing it this way is just plain wrong. But I have to admit, I was never there, I just have friends who spend 3-6 months every year there. (EDIT: okay, I read now that it should be a fictional south asian country. None the less I immediately knew that it's Thailand, so I took it for granted)

2. The "revolution" was pictured pretty cheap. I don't think, 50 extras can portray a rebellion accurately.

3. Where the heck did those people get tanks and helicopters?

If this should have been a full scale revolution, then:

4. Where was the police, the military and the government in general?

5. Where were the journalists and all the stuff that must be around when rebels/terrorists start shooting people in the head in a big city of any country?

For me it looked like a criminal gang trying to have a nice weekend, which could have been stopped within a few hours.

Even if it wasn't the scope of the movie to show the national and international reaction, they could have used a little more extras in the background to look more professional and suggest a big scale rebellion.
