I grew up on G. I. Joe, both the 12-inch figures, and "Adventure Team" trappings of the 70's , and the 3 3/4-inch "Real American Hero" of the 80's. I've got a healthy nostalgia there, no doubt.
The problem I really see in the trailers for Stephen Sommer's big-buget movie version is the "accelerator suits."
Look, this is "Real American Hero" Joe-verse, here. Where every little figure had a background file that came with them. They looked different, and, via the Larry Hama-penned cards, individual personalities. That was part of the fun, you could have your favorite Joe, something about that little toy, be it how it looked, or the person described on the file card, that called out to YOU, and there were DOZENS to pick from.
Now, we slap 'em all into these "accelerator suits," and they all look...exactly...the...same.
