Good or bad Indian representation with the sisters?

I was so confused by what they did with them. I know it's the cool new thing to be outraged about anything these days but i'm more confused and amused, not raging.

So you have these very indian girls. They don't just look indian, they dress in a very traditional way. These aren't just some random brown skin girls that could be from anywhere, they absolutely represent a culture.

So then you have Ron and Harry using them as a last resort because they couldn't get anyone else.
Not only that but they absolutely do not care for them and ignore them completely. It would have been ignorable had they mixed them up, so one of the boys had a different culture girl. Then it wouldn't felt like the movie was giving off a weird message.

Now this last part is me looking way too much into this but think about the boys. They're teenagers, they choose their dates mostly based on looks. They don't even know or care to know the girls, they ignore them. It's like the movie is saying indians are uglier, which i seriously doubt was the intention but amusing nonetheless.

PS: I'm saying indian but i'm not cultured enough to be sure. It's like i'm saying chinese instead of asians but i don't know the term for...indian looking people that includes all their countries.
