This. Not enough people give it credit. It was a pretty great show by the end of it.

what's wrong with kr being funny and not serious?

i mean has alot of fans lost their sense of humor and want things to be more violent?

No, its amazing. It just didn't garner great ratings from Japan, which has more to do with the fact that Sentai ratings have being in decline for years and less to do with the quality of the show.
And the toy sales suffered mostly from it not having a collectable gimmick, which every Rider and Sentai show for the last couple of years has had.

But from what I hear, the toys actually sold pretty well.

It's not bad, per se, but... boring. Not much really happens, as is evident by the three endings.

Kamen Rider OOO Part 2! I'm Down for this, I am completely down for this!

The show sucks, but then again I only watched half of the episodes so my judgement may be clouded.

There's a group of fans that say Go-Busters is underappreciated, and there are very few who probably flat-out hate the series. I think most people are indifferent towards it, which to me means it's a failure. I didn't care about any of the characters, and watching the series felt like a chore. News of the producer being given a second chance is great for her career, but I'm not interested unless the promotional material REEEEEEALLY grabs my interest by the eyeball stalks.

Sometimes a totally, unrelentingly goofy show is just as bad as an all serious all violent one.

This. We must know how Ankh comes back. We all know he's alive in the future but the question is: How?
