Free movie sites for kids (No inappropriate ads)?

Trying to find a place to let my kids watch 'The Super Mario Galaxy Movie' or 'Moana' without them clicking on a 'Hot Singles in your area' ad by mistake. It's impossible to find a free site that isn't 90% adult content ads. Are there any clean alternatives that are safe for a family living room?

EDIT: Someone recommended https://cine.su and with an adblocker it’s super clean, my kids are happy
