The Gobusters are learning some concept of teamwork and the episodes are somewhat dark. Why do I feel like it's having the RPM feel even if it doesn't take place in an apocalyptic setting? Somehow this "Messiah" virus is going to be a major threat to human life.
Learning how to operate the Megazords (Seriously why this name? LOL) again adds more humanity to the rangers.
It DID take some time for Gobuster-Oh to combine (it was in episode six) but then again that kind of plot was also in earlier Sentai like Jetman, Zyuranger, Dairanger, Gingaman to name a few where the combining robot didn't appear immediately) but the mecha IMO is pretty cool!
I am expecting more but I'm too stuck with other stuff. Why am I too engrossed with Chinese soaps and movies?!
