yes, you might be right. they can replace dragon with garp for saving luffy from execution and then have that final dialog (which i didn't really like, but the two plot lines must meet).

I'm not expecting the live action to ever reach the stories where the missing characters are needed. they can probably do Chopper arc, but the island of with the two giants and then crocodile, I think it's too much CGI and too many fights. then again, it's an adaptation, maybe they can make it work and re-structure it.
