Better than the first one!
I saw the first film ("Miranda" 1948) last night, and didn't care much for it. But, I saw this one tonight, and I must say that I quite enjoyed it---a whole lot! It's in Technicolor, and the scenery is very quint, not as fake and uppity snobby looking as in the first film. There are also many, many more shots of the mermaid lagoon in this film, which is breath-taking, for lack of a better phrase!
So, if you saw the first film, but were left wanting more, see this one; it's better!
"Moment by Moment" (1978), may be the most underrated movie ever! May be my fav! <3
