RE: Oh you've got to be....
From what I've seen in the poster and the idea of the entire concept over all is pathetic. Not for the concept of a live action movie for Pokemon though, but it would require redesigning the Pokemon to look more realistic. Think of the Transformers films for example, while they sucked, the designs used for the autobots and decepticons blended in with reality perfectly, something older designs for the characters wouldn't have been able to do. I've seen loads of fanart for photorealistic Pokemon attempts that make the movie poster seem pathetic. Take Charizard for instance:

It is capable of looking epic but the poster shows it looking too much like the game counterparts, making it seem bland and or "ugly" when mixing it in with live action.
