Super Sentai/YMMV

Nightmare Fuel and High Octane Nightmare Fuel: Every few seasons, there's an episode where the villains use civilians' life energy to accomplish their latest evil plans, and it always manages to be freaky.
Archive Panic: With just under 1730 episodes plus movies (not included) (as of the start of Gokaiger) and 48-51 more added each year, it's going to take quite a long time to watch them all.
- Depending on how long each show is (whether commercials count, theme song, credits) it could take anywhere from 24 days (20 min/episode) to over a month (36 days and 56 minutes at 30 min/episode) if watched continually without stopping. Both numbers use 1730 episodes stated above (still not including movies).
Complete Monster: Just because it's mainly aimed at kids, doesn't mean Sentai villains can't go off the deep end. Check out here for such examples.
Ensemble Darkhorse: Some series grow a cult following among the fanbase. Examples over the years include Dengeki Sentai Changeman, Choushinsei Flashman, Hikari Sentai Maskman, Choujin Sentai Jetman, Gosei Sentai Dairanger, Gekisou Sentai Carranger, Mirai Sentai Timeranger, Tokusou Sentai Dekaranger, Mahou Sentai Magiranger, Juken Sentai Gekiranger, and Samurai Sentai Shinkenger.
- In fact, the first three are surprisingly popular in Brazil.
Evil Is Sexy: It's more or less normal to have the heroines properly dressed, while villainesses get more sexy, revealing costumes. Subverted from time to time, though (Shizuka in Go Go Sentai Boukenger, for example, is not as sexy as she is Fanservicey).
Mood Whiplash: It can't really be helped when a Wham! Episode ends and then you get a cutesy Dancing Theme or upbeat ending song right after a shocking revelation or a battle in which the heroes are defeated in. It's here because it's typically universal.
- Worse when watching online or on DVD - the original TV broadcast would have commercials between the final scene and the end credits.
