I'll start off with a bit of my background with the series: I've seen all of Zyuranger, half of Megaranger, and varying amounts of episodes (In order of most-> least, but all less than 10) of Kakuranger, Battle Fever J, Dairanger, Goranger, Carranger, JAKQ, and Timeranger.

Anyways, I do enjoy sentai, but sometimes the amount of filler episodes gets old. I don't mind it being slightly repetitive, with the team fighting off various monsters of the week repeatedly. However, some episodes are nothing more than a monster showing up, terrorizing some people, and then getting its butt kicked. Of course, that's part of what Sentai is all about, and I like it to a degree.

So, to get to my question. Which seasons of Sentai have the least amount of "filler" episodes that don't really affect the overall plot/the most amount of plot episodes?
