When the film begins, you don't think it's a CGI or 3-D film. It looks like a Mickey Mouse film circa 1929--complete with scratchy film stock! However, when the baddie, Pete, tosses Mickey THROUGH the screen and he becomes a full-color 3-D character, you know you are in for something unique! What's next? See the film--it's well worth it.
This is an interesting case where it turns out that I liked the short more than the feature film it accompanied. In the case of "Get a Horse!", it was shown before the Disney CGI film "Frozen"--a moderately enjoyable full-length film. However, the short was indeed magical and appeared to be a real work of love. I say this because the folks who made the film did a great job of trying to replicate the exact look and sound of the very early Mickey Mouse cartoons--something that is no small feat! Unlike most 3-D films I've seen, I think it's very important you try to see "Get a Horse!" in 3-D. This is because rarely has another 3-D film tried so hard to incorporate this sort of camera-work into the film (another exception being the underrated "How to Train Your Dragon"). Most 3-D films, to me, seem as if they just tacked on the 3-D at the end and didn't plan for the use of 3-D all along (this is especially true of the live action 3-D films).
Overall, a wonderful little film that no doubt will get nominated for Best Animated Short for the Oscars. If it doesn't, I'll be incredibly surprised as the film isn't just fun but an amazing film technically.
UPDATE: I just saw this short again as part of the Oscar-nominated Animated Shorts show in selected theaters. Although it was NOT shown in 3-D this time, it didn't really seem to matter. Why I am doing this update is that in comparison to all the other nominees, "Get a Horse!" is light-years better. And, because it's so far superior I am changing my original score from 9 to 10. What a wonderful film and I like the rather playful and fun nature of the short.
