The first problem I had with the movie was the casting of younge actors to play characters I always thought of as seasoned vets of the military ie Duke is younger than me. And Cobra Commander: I always thought of him as a 40 something man in mid life crisis not the youngest cast member of the movie.
The Second problem was when I read that the movie is SCI-FI fantasy i.e StarWarsish and they will be shooting lasers rather than bullets. (cartoon not comic like Hasbro said they are basing the movie on.)
Third are the Sigma (nano) suits that make the characters look like superheros (X-men)not military. They can't even get Scarlett's uniform colour skeem to match the figure's.
My GIJoe is a realistic military based world with ficticious yet plausable characters and vehicles.
Not supersuit, laser tooting, prettyboys geared towards a younger audience other than true fans and collectors.
I'm very disappointed at this point.
