I greatly enjoy the work of Pixar (particularly Ratatouille, their boldest, most mature, and best-looking film), but 3D animation simply cannot compare to 2D animation, at least not yet. In these old 2D animations, you could laugh even looking at a single frame because there is heart, thought, and that little touch of the human put into the composition; adding in the charismatic animation simply puts it over the top and into a whole new galaxy of hilarity. I have special affection for this particular episode because it was shown before a screening of the excellent genre flick Forbidden Planet that I attended a few months back (at the wonderful Normal Theatre in Normal, IL, where they always show a cartoon before their classic films), and it was the perfect thing to whet the appetite for the heftier bit of sci-fi/space opera that followed. The look and animation of the alien in this is especially funny. It may not be one of the better Looney Tunes cartoons, but it's still pretty hysterical overall. Enjoy!
