Let's easily watch Bakuryuu Sentai Abaranger (adapted into Power Rangers Dino Thunder) by skipping all the filler episodes and only watching the most important ones. (Plot driven) You can't miss the episodes on the list because they include one of the following: 1) The first/final episode 2) Debut of a ranger or ally 3) New weapons or mecha/zords 4) Death of an important character 5) Power ups 6) Villain introduction or death 7) Backstory of a character or development
