Are you kidding me? Making fun of the special-effects of a low-budget show from
1985? Grasping at straws, man.
Commander Ibuki came off as a crazed lunatic, what with him attempting to shoot Hayate in the back and only failing because Hiryuu caused him to miss. And then, they just kind of gloss over that.
Spoiler alert: Ibuki goes lunatic in the first episode for a reason, and it's something they go back to in one of the episodes in the 30s...it's not "glossed over" at all.
That Commander Ibuki is a total asshole, getting his entire platoon killed just for five of them to become Changemen.
If you bother sticking with the show, you find out why he was completely justified in doing that
Still no clue on who these people are and where "Earth Force" comes from.
Regarding the Earth Force: maybe the Greek myths weren't myths at all, but factual accounts of ancient and mystical beasts like the phoenix, mermaid, dragon, griffin, pegasus. Maybe they were Earth's oldest beasts. Maybe tapping into their primeval power -- even symbolically -- helps defend the EARTH from alien threats.
Episode 4 is somewhat disturbing, with Hayate being a borderline pedophile (seriously, before the episode title screen, why does he want some little girl to kiss him?).
People always bring this up like it's valid -- what's wrong with them? He's trying to save the girl's pet. Kids kiss adults for helping them all the time. Furthermore, that episode is supposed to be funny from the other four's point of view -- really, Hayate is blowing off patrolling to look for a cat just to impress some girl? (They don't know it's a little girl, and just think it's the typical behavior of womanizer Hayate. This episode is meant to show there's more to than Hayate than meets the eye.)
And as for Tsurugi in his baseball outfit...really? In all of the goofy stuff you've seen in tokusatsu, THAT is something to get stuck on? Geez Louise! The whole baseball thing was written in because Tsurugi's actor was a star player in high-school, and the character puts on the uniform as a little confidence builder. What's so wrong with that?
So many of these complaints are just minor nitpicks -- I think you guys are looking too hard to find something wrong with the show.
P.S. Change Robo's design is awesome, and he's better looking than the other coneheaded mechas like Goggle Robo or Dyna Robo. Heck, he's better looking than Kamen Rider Fozzie. Personally, I prefer robos to at least look like they combined out of separate vehicles rather than a CGI hot mess like [insert robo from any Heisei sentai]. I like that thought went into how the separate mecha combine as opposed to "Let's just slap the entire crocodile on as an arm!"
EDIT: Here's something I wrote about the characters in another thread...
I think the Changeman heroes are well enough developed on page, but I always give a lot of credit to the five actors for the subtleties they provide -- they really make the characters come alive. It's just spot-on casting, IMO. I give a lot of credit to Haruki Hamada (Tsurugi) himself, who was a dramatic theater actor who held the hero side of the cast together. And I think having two veterans in the cast, like Jun Fujimaki (Ibuki) and Shouhei Yamamoto (Guiluke) made everyone step their game up. But there's little character moments the actors pay attention to -- some things that even happen in the background. I mean, pay attention to Shirou Izumi (Yuuma) some time -- he's always doing something in character, even when the spotlight's not on him. And I think having such a good cast also helped writer Hirohisa Soda step up his game.
I think your problem is...the shows where being a Sentai is the character's job doesn't really give you a peek into their off-duty personal lives, so you have to pick up clues here and there. It's like a cop show that's all business like Law & Order versus a soapy hospital drama. I think Changeman works better than most because of the cast chemistry, and the subtle things the actors provide.
