711 Ocean Drive was indeed preachy, as attested to and confirmed by the blurbs at both beginning and end. Still, I found the film interesting and entertaining (although D.O.A. remains my all-time favorite O'Brien, and one of my top favorites, overall). The character of Mal Granger really presented a sharp and unexpected contrast to that of Frank Bigelow in D.O.A. The real surprise in this film came early on when the personality of Granger, itself, did a 180-degree turnaround, from the benign, carefree and kindly telephone repairman (who insisted his co-worker accept a few bucks that he was in need of), to the ruthless, unscrupulous, and murderous "operator" for whom even a little power is seen to surely corrupt. Although the early-on character of Granger is seen for only the first 15 or 20 minutes of the film, the contrast remained with me throughout. An excellent characterization by O'Brien, as usual.
