This is a fake but it would be awesome. Yeah DBZ was bad but think about this. The whole pokemon world should atually be nothing like the anime/vg but way more like in this fake trailer, a pretty dark and violent world, I mean you have MONSTERS everywhere, some have psychic abilitys and can mind control you, you have pokemon bombs etc, you have villains who send 2m poison snakes after you, you have stuff like scyther... The only part where the VG were a bit like this was the mewtwo story.
Just check out the pokemon special manga, its not that bad but it tends to be a bit more violent and less carebear lol.
And honestly, a well done movie about a "realistic" pokemon world would actually be really interesting and Id love to see it, still it probably would be a bad idea marketing vise.
e:/ Think about digimon as an example, yeah it tends to be very cheesy and "if we believe in it we can do it" but theres also a lot of psychological stuff going on, some rather violent scenes and some really dark stuff (think about ken season2). But the digimon anime is miles above the pokemon anime because you have real villains, atmosphere, A PLOT and tension.
Getting to far ot but a rl film based on pkmn special would be awesome lol
