90210 (The CW)
Although Melrose was a complete failure, 90210 managed to find enough success to stay on the air for five seasons. After moving away from the show's initial plan to keep some original cast members floating around West Bev High, the show found a way to balance the guilty pleasure fun (pretty much anything involving Naomi) and the ridiculous (pretty much anything involving Annie). It wasn't a monster hit, but it certainly worked better than many one-and-done reboot attempts.
