As the only Jones-produced R.R. cartoon of the 1980s, with a gulf of over a decade before and after, Soup Or Sonic is a curiosity piece, and not just because of its reputation as the "one where the Coyote finally catches the Road Runner." Jones and his team appear to be scraping off the rust before our very eyes as the cartoon begins with some poorly-timed and obvious gags (Wile E. Coyote pole vaults and plummets, hoists safe only to be mashed himself, etc.). There's even a flat-out blooper when Wile E. fires up a rocket that takes off without him: he then falls to the canyon floor, with the rocket(!). However, the cartoon starts improving measurably as the animators seem to find their feet. Wile E. is at his expressive best when he checks himself for damage after an errant firecracker detonates behind him. Thinking he's survived a close call, he strikes a satisfied pose and exits doing a jaunty impression of Charlie Chaplin, showing the world he's hot stuff.
What the Coyote doesn't know is that his routine is hotter than he imagines, because his rear end is on fire! The remaining gags are also smart (the "giant fly-paper" bit is wonderful), and lead us to the climax in which the Coyote actually gets the bird! It's a clever reversal and if you've never seen it, I won't spill the goods here.
Suffice to say that catching the Road Runner was more than the Coyote bargained for. All in all, Soup Or Sonic is a 50/50 deal, and personally I regard its glass as "half full."
