Lack of story, yes, but we all expected that...since moiledeli himself commented on it. I would agree that there was little payoff by time the end came, but it is still a well-rounded film. Not to mention I found it to be a little short, even though it's over 8mins.
Overall I think it's a brilliant film. Fantastic animations, sets, cinematography, and a good amount of humor and action. The voice acting is also fantastic, as already commented on. Just about everything is fantastic in fact.
The only thing it lacks is a "meaningful" plot, sure, but I think everything else makes up for that. It was meant to be a simple, entertaining, film, and that's what it is. And yeah I'd agree the pacing was a tad too fast, but it seemed mostly steady at least.
Into the darkness once more. I walk into the unknown. To a far better life than I've ever known.
