You ever watch a movie where the protagonist, even if he's in the right, is just so pushy and unlikable that you root against him? That's how it is with me and this TV disaster movie from producer Irwin Allen. The hero here is played by Martin Milner. He spends the entire first hour of the movie yelling at everyone, including women and senior citizens, one of whom he manhandles. He's so intense in every scene. It's like he's looking for a fight, even when he's talking to his buddy or his (much younger) girlfriend. He really got on my nerves. Then the flood comes and yay he was right - I guess - but I just kept hoping the flood would get him. Really obnoxious character. I found the selfish mayor putting people's lives in danger more sympathetic than this guy. Imagine watching Jaws and you root for the shark because Brody is such a dick.
Anyway, once the flood starts the movie becomes more entertaining, although even that is limited by TV budget restrictions. The rest of the cast is solid, with Robert Culp my favorite. There's a subplot involving a bandana of his that I found more interesting than every single thing involving Milner's character.
