It's plain that Illumination is banking on a distinct visual flair while sacrificing originality of story (and, in Sing's case, distinct vocal talent). There are worse films out there, but it all makes me happy that my youngest one is 10 and I will likely be skipping more of the automatic animation viewing destinations in the future.
My teenage daughter and I spent much of the last 20 minutes laughing. Sometimes for the same reason. This is rare. If you like comedies, this will stand out. If you are suspicious of them, this will not win any awards, but it just might make you smile a time or two. You might even laugh.
