Some very nice lines and a fun performance by John Candy make this a better than average romatic comedy. Hanks is appealing and Hannah is good looking. One more good movie set in NYC.
Leonard Maltin/Plot synopsis:
Entertaining comedy about a man who falls in love with a mermaid, who's played to perfection by Hannah. Buoyant cast, winning gags make this a lot of fun, despite a tendency toward overlength. Script by Lowell Ganz, Babaloo Mandel, and Bruce Jay Friedman. Followed by a TV movie sequel in 1988.
