Cool

I thought the action in this was pretty cool. Not a fan of Gunblade's haircut but whatever.

Actually Jay's hairstyle kinda reminds me of Shun Daimonji from Kamen Rider Fourze.

Admittedly as much as I liked the core duo, they did seem to be trying a little too hard to be as clichéd looking toku characters as physically possible. And it's a shame that your a-typical toku hero is a goofy, skinny, boy band frontman. :lol

I can't fault the CGI, I prefer physical props any day of the week.
I can fault the writing, the costume design, etc.

But that origin.
Mad Scientist. Creates Super Intelligence. That he MERGES with to become a 3rd big-bad. And they unleash an ANCIENT EVIL.

Our heroes are two people who sealed away the ancient evil, but only one of them(at this point) is useful. The other is able to turn into some weird green robot-man and takes all the credit.
