two popular series sandwiching Goseiger may be a reason it was looked down upon.
Even though i did not particularly enjoyed Goseiger, i admit that it has its good points: the story and the villains are pretty good, the music is great and the overall monster designs are quite something.
Honestly the only real problems the show has are the actors/characters that remain so bland they bring everything else down, and the Header Toy gimmick which is like, really really dumb.
It is been a while after i watched the show, and after some pondering i have come to think that Goseiger can be quite enjoyable IF you have the right mindset when coming to it.
While i am at it let me present my case pro Go-onger.
I know a lot of people hate this show, and while i can agree that the show´s plot is basically a joke and the characters have no depth whatsoever, i think those aspects do not refrain from the enjoyment of the show given his shamelessly campy nature.
There is no denying it, Go-onger is the campiest super sentai season ever, and if you enjoy campy then this can be an incredibly enjoyable season.
Personally i didn´t like the show that much at first, but after 12 episodes or so i got used to its style and really came to enjoy its humor, and once you spend a decent ammount of time laughing at these characters they start to grow on you. By the time the show was ending i really didin´t want to say goodbye, and i will never regret the time i spent with these characters.
So basically, if you want mindless campy fun, Go-onger is the show for you.
