Yeah, adapting a PMD for a movie wouldn't work. I mean, they did the 6 chapter manga of the first game, and it cut out some major stuff. (No Rayquaza for starters!) And that was the lightest on plot of the series.
So they'd have to make up a new PMD style plot specifically for a movie, like FF: Spirits Within.


Dream crossover TV show/movie; A historical drama set in feudal japan, but with Pokemon.
Just think how differently japanese history would play out if there had been pokemon! And imagine what kinds of pokemon Yukimura Sanada or Mitsuhide Akechi or even Nobunaga Oda would have had... Oh, wait a minute. :P
