This was a really awkward episode; you know what they're going for, but intent isn't magic, but it is something to be taken into consideration...I'm not sure what to make of it myself.
The writers here are damn good at telegraphing just enough to keep you interested. Yeah, we know in advance that Tenaya is Dillon's sister. But that doesn't cut down on the impact of the bridge scene.
I'm sure I've mentioned it before, if not here then elsewhere, but when the writers are telegraphing it at least assures me that the writers have a plan and have thought things through, so sudden twists out of nowhere bother me much more.
The G-12/Ultrazord just has too much stuff crammed onto other stuff not doing anything in particular. And I think I can imagine what that in-character rant is going to be like.
