well, although, i have never been to Ohana, so i can't give a rating on that place
i must agree that the storyline was kinda dull, but the overall show, the different hawaiian dances that they do, the fire throwing, the food, i found to be enjoyable.
we first went there when my husband and i first got engaged. I found the whole ambiance to be very romantic and entertaining.
I would definitely recommend doing it, we plan to go again.
good luck,
jen
