The latest Aardman Animations animation. It's fun. There's almost no language. This one features nods to just about every scifi classic out there, right down to its cloning of the E.T. plot (near as I can tell given that I don't think I've seen E.T.). There's a great scene where some fake Daleks startle Tom Baker as he exits a TARDIS-y john, and many others. Conversely (unfortunately) the spook robot is little more than a Wall-E clone. I love it that the sheep are such excellent engineers.
