Dull for the most part.
I wasn't too amused - maybe because I never saw the trailer you mention.
I liked the brevity of it all and the brevity of the DDR bit was cool and made a nice contrast to the voices later on. I did chuckle there.
The simplified design for the animals was cool, though I wasn't too keen on Jebby as a character.
Anyway, For whatever reason I found it dull for the most part. Sorry I can't articulate why I feel that way.
