My rating: 6/10
Will I watch it again? Nah.
Don't be sucked into this because of the title like I was. OK, so I also wanted to see it for the underwater treasure adventure aspect. It's not so bad. You'll need to get adjust to everyone speaking clearly underwater (and with a reverb that you get when you're at a drive-in theater with the speakers hanging on the doors). It's funny at first but you get used to it.
There's some double crossing and intrigue and a fight at the end against a common enemy. And the finale has a few false endings in that each scene feels like it's about to wrap up. When it's done I was satisfied.
I dug the ending as well as the rest of the picture but not enough that I'll ever need to come back to it. Now I might be interested if a great looking widescreen print shows up. It'd be interesting to see how much of a difference that can make.
