Twitch is, by far, the best source for cute, completely harmless trailers. The site’s owner, Todd Brown, has a gift of plucking quality from the ether. Case and point, this trailer for Katie’s Journey, directed by Samuel Jorgensen.
If google is to be believed, "A little girl must reconcile with her father after a family tragedy. Little does she know that her anger fueled drawings have the power to change reality." All I know for sure is that the trailer looks – and sounds – right up my alley.
