Looking for something to bash? Even Scotty pointed out how stupid it was. A novel concept but the spaceship could've stayed... in space. The worst the locals would see there is a moving star. You'd still have line of sight directly above the volcano in space for the transporters.
The Enterprise coming out of the ocean shot was just a pure glamor shot and nothing more. It made no sense at all from a storytelling perspective. Take away that silliness and it was a good scene. I particularly liked how Spock logiced himself into breaking the PD... and for once someone got punished for breaking it.
