What is "A Plumm Summer" about?

Good question. Supposedly it's about the disappearance of Froggy Doo, the marionette star of Montana's No. 1 children's television show, who was kidnapped in the summer of 1968. It's also about a young boy's coming of age, his younger brother's obsession with said puppet, various couples having problems and nearly hitting the wall of divorce and how this affects everyone -- or not.
The film, barely watchable and actually insulting to your child's intelligence, veers wildly between broad humor (and I should mention that there is literally not one funny scene in this whole movie), sugary nostalgia and the worst melodrama.
This might be palatable if it weren't also fraught with leaden direction and horrible acting -- it's a painful thing when William Baldwin's the best actor you've got. If you want a movie that covers all the same bases perfectly, rent "The Iron Giant." But leave this one alone.
