My least favorite sentai show is, as many people before me said, also Goseiger.
The biggest problems I had with the show were mainly the story and its pacing. For me, it felt the series was just repeating the same pattern several times over, before making its big reveal with a certain character.

While such pacing can be excused with having an interesting cast of characters, making it a character driven series, Goseiger unfortunately also lacks that, in my opinion.
The ranger characters felt very inconsistent to me. For example: in the second episode, Hyde saves the day by showing effective leadership through logic. In another episode, where each of the Goseigers gets a turn in leadership, Hyde fails when he tries to open a vault by attempting every combination there is. The series was never consistent if he was an effective logic thinker, or unable to think outside the box, making him ineffective in situations where that is required.
I felt this inconsistency with almost all of the ranger characters.

It is not so bad that I regret watching it, as it has some good elements, such as one of the villains and the finale. But it is simply the least favorite of Sentai shows I have seen.

I can respect what people didn't like about Goseiger. The first time I watched it, I gave up 15 episodes in. Then I went back and watched it again and loved it. But that is just my opinion on the show.

Now Zyuranger is my next to least favorite because it was boring. Everything felt like filler except for maybe 10 episodes for the Burai arc and another 10 for the ending, but those were only part of those episodes and not the main focus of them. The kid of the week thing (although did feature ToQ 6's actor) was tiresome. It hurt my feelings how we were expected to accept that these warriors from millions of years ago, woke up to fight and quickly and easily adapted to modern day Tokyo, got jobs, and made a shit ton of friends (all under the age of 12). That was a bit much for me. There was no development of the rangers at all. Bureau had the most development, then he died *spoiler alert*. The most fleshed out character on the show was Bandora.

My feeling about Sun Vulcan are pretty much the same; the rangers were boring. They just sat around the restaurant waiting for stuff to happen, stuff happened, they went and fought, then came back and made fun of Vul Panther. Roll credits. Every single episode was like that. Even the original red ranger bounced after a while. I didn't blame him. Even the villains were boring. The biggest set back was how much they relied on Denziman for the show; I know it was meant to be a sequel to Denziman at first, but it still could have stood on its own. The only bright spot of the show was the Vul Stick; that shit was the most dynamic weapon in sentai history. It worked as a weapon against henchmen, could destroy a super computer in a single throw, or destroy a helicopter while is flew high above it's owner (all happened in the show). The power of the Vul Stick was so inconsistent, that it became a game to se what new feat it could accomplish. That was fun; the rest of the show was not.

I know that everyone has their own preference when it comes to sentai nd I think that is awesome. Like seriously; after 39 teams, there is no way that there can be a consensus on which team is the best or worst and I enjoy the debate on the matter.

Oh I know it has flaws, the whole "yay we won! Wait, a NEW enemy faction?" thing can rub many people the wrong way (I personally see it as giving me 3 seasons worth of the show in 1 season's time and how that would actually play out if you gave [favorite season of KR/SS] more seasons and why you may not want that, I personally didn't mind how they did it) and yeah, differing opinions are always welcome in discussion. :)

But you've got to admit the timing was perfect for that response. :lol

Whoa whoa whoa whoa whoa. Where is all this Dairanger backlash coming from? I don't love Dairanger as much as many (I wouldn't even place in in my top 5 list), but anyone saying it's The Worst Sentai Ever is literally crazy.

For me, Magiranger is BY FAR my least favorite, and in fact it's the only Sentai show I've ever actively disliked. Despite having some cool villains (Wolzard, Nai and Mare), I think everything else about the show is juvenile garbage. There are definitely great ideas and design elements, but I legitimately cannot stand a single one of the characters. They act like they're mentally handicapped at almost every turn. I wish Houka, especially, would die in a fire.

Good thing that nobody said that its the worst sentai. Only their least favorite. Just because something is "good" doesnt automatically mean that people will enjoy it.

This right here is why I had to post that disclaimer lol. But yeah, I don't see anybody saying that Dairanger was a bad Sentai, just that they didn't enjoy it.

Word. Misunderstood y'all. Was just surprised by the multitude of anti-Dairanger sentiments on the first page. There's typically a reverence for Dairanger, so seeing so much dislike was jarring. :lol

Well, it's less a reverence and more one person constantly vouching for it at every opportunity around here :lol

Lol, I have noticed that!

Still, in the "greater fandom," there seems to be a consensus (or as close to one that this fandom can muster :lol ) that Dairanger is a "Good Sentai Show."

Dairanger was rather above average for me, but that's really the best it could get.
