I haven't seen any Sentai before Goggle V, but Fantasy Leader said that it was starting with Goggle V that the characters started to get colorful, so I really dunno how to rate that, but if it's true, then bless you, FL. And after seeing a good chunk of Dynaman, I kinda agree that the fight scenes in Goggle V are more intense and sometimes variative than Dynaman (no offense, Dynaman fans! I still like it for what it is). You should really check it out, forget about that failed attempt if you're from Brazil just treat it as some new old-school Sentai you never watched and you should feel more home. Oh, and Miki is awesome.
I really need to up my ante of promoting it...
2. Zyuranger holds on its own, and it's not Geki/Burai that's 'the only awesome thing of Zyuranger'.Many decried that Zyuranger is a weak season, and hell I know it's pretty plagued with the 'Kid of the Week' syndrome. But I have to admit that it's not always 'Kid of The Week' even when it's not about Geki/Burai. Or when it's about MMPR nostalgia. Me, I always have a soft spot and Mei and what do you know, I find episodes featuring her entertaining, perhaps equal to the Geki/Burai episodes. Plus as said in Valsag Fantasy's blog, sometimes the 'Kid of the Week' isn't really that irritating. So yeah, I would say that Zyuranger is a pretty good show, if flawed, and should not be disliked due to the 'flaws', or overly liked merely for 'MMPR Nostalgia'.
That's about the opinions I had thus far which I think will really clash a lot with many people's, but I stand by my opinion and proud of it. Check this post often since my opinions tend to fluctuate so things may change, or I add up other conflicting opinions. I'll see you later.
