Leave aside that the economics of the situation here make no sense (how do you turn beef into rockets?), this delivers exactly as promised: a simple, rollicking tale of farmers-in-mechs versus space bugs.
The artwork and voices are both exactly on tone, clearly Disney inspired, and missing only a Space Dog to complete the scene. Sadly, the animation itself is a little lacking, being low frame rate, as though they ran out of rendering time or budget and only hit the key-frames and not the tweens.
Still, you'll quickly forget and forgive this as it rips along as a spanking pace. It's cliched and you've seen all the elements before elsewhere, but it's got an enthusiastic and unforced charm to it. Simplicity can be a virtue. Enjoy it for what it is.
