Really? I thought this was a much better execution of the idea of teasing the next hero. Their appearance was no more random than Double's, they got a decent fighting scene AND didn't actually hurt the development of the main conflict. Their quick disappearance also makes sense, considering how they're supposed to remain a secret from humans.
Double stealing the Shadow Moon battle from Decade and Kuuga after everything Shadow Moon had done to them just wasn't very satisfying. The teasing itself was nice, but Double should have defeated a minor antagonist, not the movie's main villain.
Meh, I was never concerned with the fact that the Goseigers didn't come and beat the movie villains. That didn't piss me off, that was the only positive about the Goseiger cameo was that they didn't try to outshine Shinkengers and Go-Ongers by beating up the movie villains.
My gripe about it is........Akumaro, Dayu, and Juuzo weren't even part of the main battle, nor did they even get a chance to make some form of presence in the main battle. If Akumaro and Company had made a surprise sneak attack on the Shinkenger/Go-Onger unison, and then they were stopped by the Goseiger team prior to Akumaro's next attack on the 2 teams, then I would have considered it a decent execution of a cameo.
I dunno about you guys, but it's more entertaining to me see a cameo appearance involve "interrupting" some part of the main battle instead of having some lil side battle that is un-noticeable to everyone else on the main battle field.
That's what really got to me, it just lowered the Goseigers down a notch a lil bit by not having them a "small" part in the main battle.
Sure, Kamen Rider W's cameo was utterly random and it felt un-necessary for him to beat Shadow Moon's ass like a twig (I personally hated that as well, and preferred that Kamen Rider W had just shafted Ikadevil while Decade & Kuuga whipped Shadow Moon's punk ass instead), but there was more entertaining because they actually had a role in the
main battle instead of some lil side battle that no1 on the main battle field did not even know occurred.
