This show, plainly, is formulaic. Yet, I love Hawaii, so I watch. I don't expect intricate plot-lines; this show is designed for fluff.
Episodes like this one are cheap to produce, too bad they often also come off as cheap. The actor from Windtalkers is excellent, but one can only work with the material they're given.
My biggest grievances with this episode come in the casual stroll with Danno, Chin, and the navy psychiatrist whilst a major standoff is underway. The pacing is clearly off. Then Steve stops to have a conversation instead of proceeding directly to the pilothouse. Really people? Really?
