Wily E. Coyote is chasing the roadrunner, who moves fast enough to easily clear a canyon. With Wily unable to get up the speed necessary to clear it as easily, he falls back onto a series of devices to try and get across to the waiting roadrunner.
You either like the Coyote/roadrunner cartoons or you don't, but that doesn't mean that there aren't good one and bad ones just because they use the same formula. Here the film really lacks a bit of spark and is surprisingly static. Basically the repeating joke is that Wily tries to get across the canyon but keeps falling down. The question `why, when he climbs back up, doesn't he just climb up the other side?' should be dismissed from that start, as logic has no place here.
The very static action, and the fact that it is so repetitive, is a problem as it takes away the very nature of the cartoons in terms of fluidity and energy. Usually these cartoons keep moving so fast that the gags pile up to being funny; here it is just one staged event after another and it doesn't work as well. The animation is pretty basic but it has enough about it not to be awful. The characters are not as good as usual (not that they are ever that well developed) but they look basic and act different from usual.
Overall this is an OK cartoon for those that like Roadrunner stuff, but this is a weak entry in their enjoyable series.
