Old-ish Sinhala Movie

This is a Sinhala movie from my childhood. It's not that Old, like from the early 2000-2010s, I don't actually remember when it came out... It's generally feel good, family movie that I think deserves to be known internationally.

Hogana Pokuna 

Here's the link to it on YouTube, this version has English subtitles. The title can be directly translated to 'The Singing Pond'. If you want to go into the movie completely blind, stop reading now.

Just a small synopsis of the movie: The students of a village school have never seen the ocean, and their newest teacher from the city makes it her mission to take them to it. A lot of the movie bases itself on Sri Lankan communities, and some things may not make sense to Western audiences. I'm willing to answer any question, if there are any.
