Mermaid disappeared in a ten-foot-deep pool. That's pretty imaginative! I also liked how slow and detailed the pace of the narrative was up to that point when the dog jumped in the pool and how quickly all the important transformations have taken place.

I can imagine how the operator goes over every little detail. Then suddenly the director tells him "Hey, Brian, we ain't got the whole life to shoot this flick. Finish it up quickly. The rest we will do in the editing room!"

Way to go!
