Seth is very right, the bible doesn't say anything about frog rains. Many of the characters are very hard pressed but are still struggling to do the right thing. The pouring of frogs comes when most of the characters are about to come to some sort of conclusion to their troubles. Also the two most prominent fathers in the movie die shortly after.
Simple rain can certainly represent a fresh start.
If I recall right the movie is quite dark from beginning right through to the end when after the frograin the sun shines for the first time. The frograin is a biblical reference. There's nothing in the bible about frog-rain. All rights reserved.
