A live-action Pokemon film doesn't fill me with optimism.
I'm not particularly keen on all the 3D models used in Pokemon games like X/Y, Mystery Dungeon or the 3DS Pokedex.
Something about them can seem a little uncanny compared to the 2D depictions.
And given how hit-and-miss modern CGI can be, particularly when blending CG creattures in shots with real people, I'm not particularly confident in any studios ability to get it righht.
