other than eddie and possibly larry, i dont think any other non-cleaver had that much contribution to the series. i think all this lumpy talk is merely because he died. lumpy is barely on at all in the first year, and he only slowly becomes a friend. i am still on the second year, as it is the show i am currently watching. the thing that really makes the show is that it is well written. ward and june have great dialogue. and while i think ward is actually a good actor, june is good some time. and other times, the writing saves her. of the boys, i think beaver does better acting than wally. the only slightly irritating aspect of wally's acting is his constant action of looking down. it is not normal, in the sense that i have never seen a real person do this. although i suspect that it is intentional. so while it may not be a defect in wally's acting, i dont think it helps the character of wally.
