And it's not even good animation, my eight year old nephew has an iPad app that creates using a similarly style.
No expense spared obviously
The thing is Songkran makes for some amazing fun filled visuals, sure we know the truth, but for marketing purposes, young'ish soapy randy people spraying water, dancing in the street, cut in some random 2 second hottie shots, makes for a good promo video. Tourists don't really care about the origins & ceremony, they're hot, wet, horny and just want to have fun with water guns.
Divert some of that submarine money, hire a pro director and film crew, do it properly. Not this year though, pooch is screwed already.
