First off, I can't help but point out the "protecting the island" line that belonged on Lost. Either it was a big coincidence or an intentional shout out, considering Jin was standing right there. Either way, it made me smile.
The rest of "Ko'olauloa," however, was pretty boring. It was a Kono-centric episode, but failed to give her any depth. Okay, so there's this guy and they haven't seen each other for years and he may be the killer (though every viewer knows he's not). We learn Kono is willing to put her work in front of her personal feelings. And?
The larger story deals with paternity and paternity and how evil corporations are, an wholly unoriginal, boring plot. But again, the visuals were stunning, especially the ceremony at the end of the episode. Is that enough to keep watching?
Score: 8.0/10
