The revamped Hawaii Five-0 serves its purpose, showcasing how cool Hawaii looks amidst a bunch of action scenes. Clearly CBS didn't skimp on the money, perhaps the one factor which makes the show worth watching. The dialogue is leaden, the plot is generic, and the characters equally boring.
Given the ratings for the premiere, an impressive 3.8 for the 18/49 demo, Five-0 will most likely succeed and have many seasons. It'll also mark Alex O'Loughlin's first win, after CBS trotted him out on several shows. But the success of the show won't hinge on him--or at least his acting. (To be honest, his acting still didn't impress me, but neither did the other cast members.) What matters is if each episode can be as exciting as the pilot.
I'd like to watch more episodes to see if the rest of the episodes do maintain the action, but my Monday schedule is loaded, so it's an uncertainty.
Score: 8.5/10
